The Qur’anic Root S R R

1. The Root in Early and Pre-Islamic Arabic

Secrets, Hidden Matters, and What Remains Out of Sight

In early Arabic, سِرّ (sirr) stood in contrast to openness and public announcement. Something kept concealed from others, speech that was not made public, or a matter that remained within belonged to this field.

One early expression in this family was سَرَار الشهر (sarār al-shahr): the final night or nights of the month, when the crescent disappears from view. Early poetry and rajaz verse also record سَرَارها (sarāruhā) for this phase of the moon. This use shows that “disappearing from view” was among the root’s early semantic branches.

Poetry attributed to Imruʾ al-Qays also includes يُسِرُّونَ (yusirrūna) in the well-known verse:

تَجَاوَزْتُ أَحْرَاسًا إِلَيْهَا وَمَعْشَرًا
عَلَيَّ حِرَاصًا لَوْ يُسِرُّونَ مَقْتَلِي

Tajāwaztu aḥrāsan ilayhā wa-maʿsharan / ʿalayya ḥirāṣan law yusirrūna maqtalī.

This verse has been transmitted in that form. Yet the evidence has long been subject to disagreement over its reading and interpretation, and some transmitters read it with a different letter. It cannot therefore serve on its own as the basis for a separate meaning of the root.

This disagreement also becomes relevant below in the discussion of أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata).

Joy and Being Joyful

The branch of joy was also known before Islam. The pre-Islamic poet al-Mutalammis al-Ḍubaʿī says in describing someone:

أَنْتَ مَثْبُورٌ غَوِيٌّ مُتْرَفٌ
ذُو غَوَايَاتٍ وَمَسْرُورٌ بَطِرُ

Anta mathbūrun ghawiyyun mutrafun / dhū ghawāyātin wa-masrūrun baṭiru.

Here مَسْرُور (masrūr) clearly expresses a state of joy and satisfaction. The Qur’anic use of مَسْرُور (masrūr) and سُرُور (surūr) therefore continues a recognized linguistic field, rather than a meaning created after the Qur’an.

The Interior, the Central Part, and a Place of Settlement

Early Arabic also used other forms in this family for the inner or central part of something. Expressions such as سَرَارَة الوادي (sarārat al-wādī), for the choice or middle part of a valley, and سُرَّة (surrah), for the navel, belong to this field.

In the poetry of al-Aʿshā, السَّرِير (al-sarīr) is also used for the soft inner part of a reed. This use shows that sarīr in early Arabic was not only the name of a couch, and that the word family could also be connected with the interior, the underlying part, or the place where something rests.

These observations do not establish that the Qur’anic meaning “couch” necessarily developed from “interior,” or that joy necessarily derived from “settling within.” These are related linguistic branches, but the precise historical path between them is uncertain.

2. The Branch of Secrets, Hidden Matters, and Privacy

Most Qur’anic uses of S R R belong to this field. سِرّ (sirr), أَسَرَّ (asarra), إِسْرَار (isrār), and سَرَائِر (sarāʾir) each describe, from a different angle, something outside the public and visible sphere.

سِرّ (sirr) in Contrast to Jahr and ʿAlāniyah

One of the clearest examples is:

وَهُوَ اللَّهُ فِي السَّمَاوَاتِ وَفِي الْأَرْضِ يَعْلَمُ سِرَّكُمْ وَجَهْرَكُمْ

Wa-huwa Allāhu fī al-samāwāti wa-fī al-arḍi yaʿlamu sirrakum wa-jahrakum.

He is The God, the One worshipped in the heavens and on earth; He knows what you conceal and what you make open.

Al-Anam 6:3

سِرَّكُمْ (sirrakum, what you keep hidden) appears in contrast to جَهْرَكُمْ (jahrakum, what you make open). Sirr here is therefore not merely a “secret” in the sense of confidential information told to another person; it can encompass anything within a person’s non-public sphere.

Other ayahs also state:

يَعْلَمُ سِرَّهُمْ وَنَجْوَاهُمْ

Yaʿlamu sirrahum wa-najwāhum.

He knows their secrets and their private conversation.

At-Tawbah 9:78

And:

أَمْ يَحْسَبُونَ أَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوَاهُمْ

Am yaḥsabūna annā lā nasmaʿu sirrahum wa-najwāhum.

Or do they think that We do not hear their secrets and their private conversation?

Az-Zukhruf 43:80

The pairing of سِرّ (sirr) and نَجْوَى (najwā) shows that they are not precisely the same thing. Najwā is usually private communication or conversation between people; sirr can be broader, including something that has not even been told to anyone else and remains within.

سِرًّا (sirran) Meaning Privately

In several ayahs, سِرًّا (sirran) appears in contrast to عَلَانِيَةً (ʿalāniyatan, openly):

الَّذِينَ يُنْفِقُونَ أَمْوَالَهُمْ بِاللَّيْلِ وَالنَّهَارِ سِرًّا وَعَلَانِيَةً

Alladhīna yunfiqūna amwālahum bi-al-layli wa-al-nahāri sirran wa-ʿalāniyatan.

Those who spend their wealth by night and day, privately and openly.

Al-Baqarah 2:274

In such a use, sirr does not name a secret; it describes how an act is performed: outside the public sphere.

The same contrast appears in Ar-Rad 13:22, Ibrahim 14:31, An-Nahl 16:75, and Fatir 35:29. Together, these ayahs provide some of the clearest evidence for the core of “non-public and private” in this branch of the root.

أَسَرَّ (asarra): Keeping Something Hidden

The verb أَسَرَّ (asarra) occurs eighteen times in the Qur’an. One of the clearest examples appears in the account of Joseph:

فَأَسَرَّهَا يُوسُفُ فِي نَفْسِهِ وَلَمْ يُبْدِهَا لَهُمْ

Fa-asarrahā Yūsufu fī nafsihi wa-lam yubdihā lahum.

Joseph kept it within himself and did not disclose it to them.

Yusuf 12:77

The second clause, وَلَمْ يُبْدِهَا لَهُمْ (wa-lam yubdihā lahum, and did not disclose it to them), clarifies the first. What Joseph أَسَرَّ (asarra) was something he kept within himself and did not reveal.

The same contrast appears in other ayahs:

أَوَلَا يَعْلَمُونَ أَنَّ اللَّهَ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ

Awa-lā yaʿlamūna anna Allāha yaʿlamu mā yusirrūna wa-mā yuʿlinūna.

Do they not know that The God knows what they conceal and what they make public?

Al-Baqarah 2:77

And:

وَأَسِرُّوا قَوْلَكُمْ أَوِ اجْهَرُوا بِهِ

Wa-asirrū qawlakum awi ijharū bihi.

Keep your speech private, or speak it openly.

Al-Mulk 67:13

In the Qur’an’s clear uses, أَسَرَّ (asarra) is therefore connected with keeping something outside the sphere of public announcement and disclosure.

أَسَرَّ إِلَى (asarra ilā): Saying Something Privately to Someone

When the verb occurs with إِلَى (ilā, to), the construction changes:

وَإِذْ أَسَرَّ النَّبِيُّ إِلَىٰ بَعْضِ أَزْوَاجِهِ حَدِيثًا

Wa-idh asarra al-nabiyyu ilā baʿḍi azwājihi ḥadīthan.

And when the Prophet privately shared a statement with one of his wives.

At-Tahrim 66:3

Here the statement was not concealed from its recipient; it was told to that person and kept non-public in relation to others.

Two constructions must therefore be distinguished:

أَسَرَّ الشَّيْءَ (asarra al-shayʾa): he concealed something or kept it within.

أَسَرَّ إِلَى فُلَانٍ حَدِيثًا (asarra ilā fulānin ḥadīthan): he privately shared a statement with someone.

The difference comes from the preposition and sentence construction, not from two different roots.

أَسَرُّوا النَّجْوَى (asarrū al-najwā)

The Qur’an says:

وَأَسَرُّوا النَّجْوَى

Wa-asarrū al-najwā.

They kept the private conversation concealed.

Ta-Ha 20:62

The same construction also appears in Al-Anbiya 21:3.

نَجْوَى (najwā) is itself private conversation, while أَسَرُّوا (asarrū) emphasizes keeping it non-public. The two words are therefore not a meaningless repetition: one identifies the type of communication, the other its remaining concealed.

أَسَرُّوهُ بِضَاعَةً (asarrūhu biḍāʿatan)

In the account of Joseph we read:

وَأَسَرُّوهُ بِضَاعَةً

Wa-asarrūhu biḍāʿatan.

And they concealed him as merchandise.

Yusuf 12:19

The subject here is not speech, but Joseph himself and his situation. The caravan members did not disclose the truth about his presence and status, and counted him among their goods.

This ayah shows that أَسَرَّ (asarra) is not restricted to a spoken secret: a person, a decision, a feeling, or another matter can also be kept hidden.

أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata): Did They Conceal or Reveal It?

The expression أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata) appears in Yunus 10:54 and Saba 34:33:

وَأَسَرُّوا النَّدَامَةَ لَمَّا رَأَوُا الْعَذَابَ

Wa-asarrū al-nadāmata lammā raʾawū al-ʿadhāba.

When they saw the punishment, they kept their remorse within.

Yunus 10:54

The early lexical tradition includes a report treating أَسَرَّ (asarra) as a word with two opposite meanings, recording both “he concealed” and “he revealed.”

That report, however, has itself long been disputed. Part of the poetic evidence invoked is also transmitted with an alternative reading, while many clear Qur’anic uses place أَسَرَّ (asarra) in contrast to announcing, speaking openly, disclosing, and appearing.

In Al-Maidah we also read:

فَيُصْبِحُوا عَلَىٰ مَا أَسَرُّوا فِي أَنْفُسِهِمْ نَادِمِينَ

Fa-yuṣbiḥū ʿalā mā asarrū fī anfusihim nādimīna.

Then they would become remorseful over what they had concealed within themselves.

Al-Maidah 5:52

In this ayah, أَسَرُّوا فِي أَنْفُسِهِمْ (asarrū fī anfusihim) clearly refers to keeping something within.

Within the root’s network of Qur’anic uses, rendering أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata) as “they concealed their remorse within” or “they suppressed their remorse” therefore has stronger support from the Qur’an itself. “They revealed” should remain a disputed lexical report, rather than a basic meaning imposed on these ayahs.

إِسْرَار (isrār)

The verbal noun إِسْرَار (isrār) occurs twice. In Nuh 71:9:

ثُمَّ إِنِّي أَعْلَنْتُ لَهُمْ وَأَسْرَرْتُ لَهُمْ إِسْرَارًا

Thumma innī aʿlantu lahum wa-asrartu lahum isrāran.

Then I announced openly to them and spoke to them privately.

Nuh 71:9

The contrast between أَعْلَنْتُ (aʿlantu, I announced openly) and أَسْرَرْتُ (asrartu, I spoke privately) shows that two modes of communication are involved: a public call and a non-public or private call.

Muhammad 47:26 also states:

وَاللَّهُ يَعْلَمُ إِسْرَارَهُمْ

Wa-Allāhu yaʿlamu isrārahum.

And The God knows their concealment.

Muhammad 47:26

Here the verbal noun can encompass both the act of concealing and what took place in secret.

سَرَائِر (sarāʾir): What Lies Hidden Within

سَرَائِر (sarāʾir) occurs only once in the Qur’an:

يَوْمَ تُبْلَى السَّرَائِرُ

Yawma tublā al-sarāʾiru.

The day when hidden matters are put to the test.

At-Tariq 86:9

سَرَائِر (sarāʾir) is the plural of سَرِيرَة (sarīrah). The word can encompass such matters as purpose, intention, belief, a decision, or a concealed act.

The important point is that the Qur’an does not say that only “confidential statements” are tested. The field of سريرة (sarīrah) is broader than a spoken secret and approaches what lies behind a person’s outward appearance.

3. “لَا تُوَاعِدُوهُنَّ سِرًّا” (lā tuwāʿidūhunna sirran) and the Range of Sirr

Al-Baqarah 2:235 states:

وَلَٰكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّا أَن تَقُولُوا قَوْلًا مَّعْرُوفًا

Wa-lākin lā tuwāʿidūhunna sirran illā an taqūlū qawlan maʿrūfan.

But do not make a secret promise with them, except to speak a recognized word.

Al-Baqarah 2:235

This is one of the uses that requires particular care.

In early Arabic, سِرّ (sirr), in addition to its general meaning of a secret or hidden matter, was sometimes used euphemistically for sexual or marital relations, since such relations belonged to the private sphere. Early lexicographers and commentators therefore proposed several possibilities for سِرًّا (sirran) in this ayah: a secret promise of marriage, a private commitment, or speech and a relationship with sexual implications.

The ayah itself, however, provides a clear framework. Before this expression, it discusses mentioning the women and indirectly indicating an interest in marriage; afterward come قَوْلًا مَعْرُوفًا (qawlan maʿrūfan, a recognized word) and then عُقْدَةَ النِّكَاحِ (ʿuqdata al-nikāḥi, the marriage bond).

One specific interpretation reported in later periods should therefore not enter the translation as the sole lexical meaning of سِرًّا (sirran). What the construction shows with greater confidence is a distinction between an arrangement of promises made in a hidden, private sphere and qawl maʿrūf, recognized speech.

“Secretly” or “a secret promise” is therefore a more cautious rendering for the base text, while the earlier use of sirr for an intimate relationship can be mentioned in the lexical explanation.

4. The Branch of Joy, Satisfaction, and Favorable Conditions

The root’s second branch in the Qur’an concerns joy and a pleasant state. It appears in تَسُرُّ (tasurru), سُرُور (surūr), مَسْرُور (masrūr), and سَرَّاء (sarrāʾ).

تَسُرُّ (tasurru): Bringing Joy

The root’s simple verb occurs only once:

بَقَرَةٌ صَفْرَاءُ فَاقِعٌ لَوْنُهَا تَسُرُّ النَّاظِرِينَ

Baqaratun ṣafrāʾu fāqiʿun lawnuhā tasurru al-nāẓirīna.

A yellow cow, bright in color, that brings joy to those who look upon it.

Al-Baqarah 2:69

تَسُرُّ (tasurru) is transitive: something produces a state of joy or satisfaction in the viewer.

This ayah does not show that surūr must be a deep, lasting, or spiritual state. In this context, even visual beauty can cause it. The intensity and duration of the joy should therefore not be derived from the root itself.

سُرُور (surūr)

Al-Insan 76:11 states:

فَوَقَاهُمُ اللَّهُ شَرَّ ذَٰلِكَ الْيَوْمِ وَلَقَّاهُمْ نَضْرَةً وَسُرُورًا

Fa-waqāhumu Allāhu sharra dhālika al-yawmi wa-laqqāhum naḍratan wa-surūran.

The God protected them from the evil of that day and brought them radiance and joy.

Al-Insan 76:11

سُرُور (surūr) here is a state of joy and satisfaction.

Its pairing with نَضْرَة (naḍrah, radiance) is noteworthy, but should not become an absolute rule that naḍrah is always outward and surūr always inward. In this ayah, one points more toward radiance and the other toward joy, forming a complementary picture.

مَسْرُور (masrūr)

It occurs twice in Al-Inshiqaq:

وَيَنْقَلِبُ إِلَىٰ أَهْلِهِ مَسْرُورًا

Wa-yanqalibu ilā ahlihi masrūran.

And he returns to his people joyful.

Al-Inshiqaq 84:9

And:

إِنَّهُ كَانَ فِي أَهْلِهِ مَسْرُورًا

Innahu kāna fī ahlihi masrūran.

He had been joyful among his people.

Al-Inshiqaq 84:13

These two ayahs contain an important point. In one setting, مَسْرُور (masrūr) describes someone with a favorable outcome; in the other, it describes someone who was joyful in his former life but held a mistaken belief about his return.

Joy itself therefore has no fixed moral value. Its value comes from its cause, object, and outcome in context.

سَرَّاء (sarrāʾ) in Contrast to ضَرَّاء (ḍarrāʾ)

سَرَّاء (sarrāʾ) occurs twice in the Qur’an, both times in contrast to ضَرَّاء (ḍarrāʾ):

الَّذِينَ يُنفِقُونَ فِي السَّرَّاءِ وَالضَّرَّاءِ

Alladhīna yunfiqūna fī al-sarrāʾi wa-al-ḍarrāʾi.

Those who spend in ease and hardship.

Al-Imran 3:134

And:

قَدْ مَسَّ آبَاءَنَا الضَّرَّاءُ وَالسَّرَّاءُ

Qad massa ābāʾanā al-ḍarrāʾu wa-al-sarrāʾu.

Hardship and ease also touched our fathers.

Al-Araf 7:95

In these two ayahs, سَرَّاء (sarrāʾ) is not merely a psychological feeling of joy. Its contrast with ضَرَّاء (ḍarrāʾ) shows that favorable living conditions are set against harmful and difficult conditions.

Depending on context, “ease,” “plenty,” “relief,” or “favorable conditions” can convey this meaning.

This use likewise carries no independent moral value. Ease can provide a setting for gratitude, heedlessness, testing, or other behavior; the word itself simply describes the condition.

5. سُرُر (surur): Couches and Places for Sitting

سُرُر (surur) is the plural of سَرِير (sarīr) and occurs six times in the Qur’an. Unlike the branches of secrecy and joy, this concerns a physical object and a place for sitting, resting, or reclining.

For example:

إِخْوَانًا عَلَىٰ سُرُرٍ مُّتَقَابِلِينَ

Ikhwānan ʿalā sururin mutaqābilīna.

As brothers, on couches, facing one another.

Al-Hijr 15:47

And:

مُتَّكِئِينَ عَلَىٰ سُرُرٍ مَّصْفُوفَةٍ

Muttakiʾīna ʿalā sururin maṣfūfatin.

Reclining on couches arranged in rows.

At-Tur 52:20

And:

فِيهَا سُرُرٌ مَّرْفُوعَةٌ

Fīhā sururun marfūʿatun.

Therein are raised couches.

Al-Ghashiyah 88:13

The word سُرُر (surur) in these ayahs identifies only the type of place. Features such as facing one another, being arranged in rows, being raised, or being adorned come from the accompanying descriptions, not from the root itself.

For example, in سُرُرٍ مُّتَقَابِلِينَ (sururin mutaqābilīna), facing one another is understood from مُتَقَابِلِينَ (mutaqābilīna). In سُرُرٍ مَّصْفُوفَةٍ (sururin maṣfūfatin), arrangement in rows comes from مَصْفُوفَةٍ (maṣfūfatin). In سُرُرٌ مَّرْفُوعَةٌ (sururun marfūʿatun), height comes from مَرْفُوعَةٌ (marfūʿatun).

This distinction prevents all the features of Qur’anic couches from being placed inside the definition of the root S R R.

Does سُرُر (surur) Derive from Joy?

The resemblance between سُرُر (surur) and سُرُور (surūr) may suggest that a sarīr received its name because it brings joy and ease.

That connection may be semantically appealing, but there is insufficient evidence to present it as the word’s historical origin.

In early Arabic, سَرِير (sarīr) was used not only for a couch but also for the inner part of certain things or the place where they rest. A couch, in turn, is naturally a place where the body settles and rests.

It is therefore better to say that سَرِير (sarīr) belongs to this root family and has the clear Qur’anic meaning “a couch or a place for sitting and reclining,” without claiming that it definitely derives from surūr or that all these meanings arose from a single historical image.

6. Comparison with Related Words and Roots

S R R (sirr) Compared with K T M (katama)

کَتَمَ (katama) emphasizes keeping something back and not disclosing it. A person possesses knowledge or information but prevents it from becoming apparent.

سِرّ (sirr) is broader. Something can be sirr even if no one has consciously concealed it—for example, something that exists only within a person.

Moreover, أَسَرَّ إِلَى (asarra ilā) can mean privately sharing something with another person, whereas kitmān places greater emphasis on withholding and keeping something concealed.

S R R (sirr) Compared with N J W (najwā)

The Qur’an itself places the two together:

سِرَّهُمْ وَنَجْوَاهُمْ

Sirrahum wa-najwāhum — their secrets and their private conversation.

نَجْوَى (najwā) is usually private conversation between people.

سِرّ (sirr) can be speech, an intention, a feeling, or a hidden matter that has not even been shared with another person yet.

Every najwā is therefore non-public, but not every sirr is necessarily najwā.

S R R (surūr) Compared with F R Ḥ (faraḥ)

Both roots belong to the field of joy, but they are not completely interchangeable.

سُرُور (surūr) in Qur’anic usage denotes a state of joy and satisfaction.

فَرَح (faraḥ) also expresses joy, but appears in a wider variety of Qur’anic contexts describing a person’s response to what they have gained or what has occurred, and is sometimes accompanied by exultant excess, self-admiration, or unjustified delight.

An absolute boundary should not, however, be drawn in which surūr is always calm and faraḥ always excited or blameworthy. The moral direction of both comes from context.

S R R (surur) Compared with A R K (arāʾik)

سُرُر (surur) denotes couches or places for sitting and reclining.

أَرَائِك (arāʾik) is also used in the Qur’an for places of ease and reclining, and approaches surur in some contexts.

Equating the two precisely without a separate examination of A R K would be unwarranted. In translating each ayah, its accompanying descriptions and setting must also be considered.

7. Translation Suggestions for Forqan

No single equivalent suits every derivative of S R R.

سِرّ (sirr):
A secret, what is hidden, a concealed matter, non-public content; depending on context.

سِرًّا (sirran):
Secretly, privately, in private.

أَسَرَّ الشَّيْءَ (asarra al-shayʾa):
He concealed it; kept it within; did not disclose it.

أَسَرَّ إِلَيْهِ حَدِيثًا (asarra ilayhi ḥadīthan):
He privately shared a statement with him; told him something in confidence.

أَسَرَّ الْقَوْلَ (asarra al-qawla):
He spoke privately; expressed his words outside the public sphere.

أَسَرُّوا النَّجْوَى (asarrū al-najwā):
They kept their private conversation concealed.

أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata):
They kept their remorse within; they suppressed their remorse.

“They revealed” may be mentioned as a disputed lexical report, but receives weaker support from the range of Qur’anic uses for inclusion in the base translation.

إِسْرَار (isrār):
Concealing, speaking privately, or non-public behavior; according to the construction.

سَرَائِر (sarāʾir):
Hidden matters, what is concealed within, hidden states and realities.

تَسُرُّ (tasurru):
It brings joy; it pleases.

سُرُور (surūr):
Joy, gladness, satisfaction.

مَسْرُور (masrūr):
Joyful, pleased.

سَرَّاء (sarrāʾ):
Ease, plenty, relief, favorable conditions; especially in contrast to ضَرَّاء (ḍarrāʾ).

سُرُر (surur):
Couches, places for sitting and reclining.

In ayahs concerning the Garden, features such as being raised, arranged in rows, facing one another, or woven and adorned must be translated from the accompanying descriptions, rather than placed within the basic meaning of سُرُر (surur).

Conclusion

The root S R R forms a family with several branches in the Qur’an. Its uses should not all be reduced to a single definite image.

Its largest branch concerns being hidden and remaining non-public. سِرّ (sirr) is a hidden matter; أَسَرَّ (asarra) can involve keeping something concealed or privately sharing speech with another person; إِسْرَار (isrār) expresses a concealed act or private communication; and سَرَائِر (sarāʾir) extends to a person’s hidden, inward matters.

The Qur’an repeatedly clarifies this field through opposites such as jahr, open expression; iʿlān, announcement; ʿalāniyah, openness; and ibdāʾ, disclosure. In the old disagreement over أَسَرُّوا النَّدَامَةَ (asarrū al-nadāmata), concealment therefore accords more closely with the broader network of Qur’anic uses, while “revealing” should remain a disputed lexical possibility.

The second branch concerns joy and favorable conditions. تَسُرُّ (tasurru) describes what brings joy; سُرُور (surūr) is joy itself; مَسْرُور (masrūr) describes a joyful person; and سَرَّاء (sarrāʾ), in contrast to ضَرَّاء (ḍarrāʾ), expresses conditions of ease and plenty. This branch is likewise morally neutral: joy or ease does not by itself signify divine approval or the rightness of a person’s behavior.

The third branch is سُرُر (surur), the plural of سَرِير (sarīr): couches and places for sitting and reclining. The Qur’an gives these couches various descriptions, but those features come from the accompanying words and should not be included in the meaning of the root itself.

Pre-Islamic Arabic also knew at least the branch of hiddenness, the branch of joy, and some uses connected with the interior and sarīr. The presence of all these branches within one linguistic family does not, however, mean that their derivational history is fully known.

A concise and cautious definition of this root is therefore:

S R R: A linguistic family with several Qur’anic branches: in one, what is hidden, private, and kept from disclosure; in another, joy, satisfaction, and favorable conditions; and in the branch of sarīr, a place for sitting and settling. The precise historical connection between these branches should not be assumed without firm evidence.

This definition preserves the broad field of secrecy and hiddenness, keeps joy and sarrāʾ distinct from it, and prevents the resemblance between surur and surūr from becoming an invented etymology.
