Why this shape?What each of the 13 patterns does
What each pattern does. The pattern gives a tendency, not a rule: many words have drifted into meanings of their own.
The pattern machinePour the root into a pattern; see whether the word exists
Choose a pattern; the root's letters pour into it. Then see whether the word exists in our sources. The machine makes shapes; only usage makes words.
Not in our sources. A possible shape, not a word we can show: the Quran, the library and Lane do not have it for this root.
Place noun with -a. The place noun with the feminine -a. Sometimes it is only a variant of mafʿal; often it names the place where a thing is found in abundance (maʾsada, 'a place full of lions'). So maktab is the place of writing, and maktaba, where writings are gathered: a library, a bookshop. Our summary AI
But: maktaba is not in our classical dictionaries for k-t-b: Lane and al-Jawharī give maktab ('a school'), none gives maktaba. Its sense of 'library, bookshop' fits the pattern of abundance, but that is our reading of the pattern, not a classical entry. Many mafʿala words are single items of usage (maqbara 'cemetery'), which the grammarians call heard, not formed by rule.

ما يكون مفعلة لازمة لها الهاء والفتحة … وذلك إذا أردت أن تكثر الشيء بالمكان، وذلك قولك: أرض مسبعة، ومأسدة

This root has a weak or doubled letter, so real words change shape (qāla → qāʾil, not qāwil); the machine pours the letters in as they are, and matches attested words by their regular pattern.
About thisWhat “attested” means here; the sources
Attested means found in our data: the Quranic Arabic Corpus (lemmas, verb Forms, participles, verbal nouns, plurals), the library's words (automatic analysis), Lane's Lexicon (his headwords, the Forms he numbers, the verbal nouns and plurals he names) and Ibn Fāris's entry. Nothing is generated for this list. Meanings are Lane's first gloss in his entry, or else the analyser's gloss (“auto”). Vowelling follows the corpus, then Lane, then the analyser; verbs are given in the regular perfect. Lane's Lexicon thins out after qāf, and a few of his entries cover several roots at once: those roots show no Lane. The patterns, written with ف ع ل, are computed by us.

About thisal-Khalīl, Ibn Jinnī, Ibn Fāris; the counts across the dictionary
al-Khalīl (d. c. 170/786), Kitāb al-ʿAyn, as transmitted by al-Layth: a two-letter word “turns in two ways”, a three-letter word “in six ways” (masdūsa), four letters in 24, five in 120; “its used forms are written down and its unused ones dropped” (line 975 ↗). The dictionary is built on this: each chapter takes a set of letters and names which orders are used (mustaʿmal) and which unused (muhmal). The ring shows that verdict, from the chapter heading as edited (documented in the text; how much of the book is al-Khalīl's own is disputed).
A reported total. al-Suyūṭī transmits, from Ḥamza al-Iṣfahānī, that al-Khalīl put the possible forms, used and unused, of two to five letters at 12,305,412 (al-Muzhir, line 1347 ↗). It is reported, not found in the ʿAyn. It equals exactly the arrangements of 2 to 5 different letters out of 28 (756 + 19,656 + 491,400 + 11,793,600); the breakdown printed beside it is corrupt, and al-Zubaydī's count, given next, differs (6,659,400).
Ibn Jinnī (d. 392/1002), al-Khaṣāʾiṣ, names the greater derivation (al-ishtiqāq al-akbar): bind a three-letter root and its six orders to one meaning, and bring stray members back “by the subtlety of the craft and interpretation” (line 7536 ↗). He says himself that it does not hold for every root (line 167 ↗; line 7603 ↗).
Ibn Fāris (d. 395/1004) gives each root its own aṣl and treats a rearranged word as maqlūb, “turned round”, and so not a root of its own: “j-b-dh is not a root, because it is a single word, turned round” (Maqāyīs, line 6147 ↗). The ring sets his aṣl for each order side by side; whether they meet is the question.
Neighbours on the ring differ by one swap of two letters.
The critique. A source quoted by al-Suyūṭī calls the greater derivation Ibn Jinnī's innovation, “not relied on in the language” (al-Muzhir, line 6159 ↗).
The other axis. The root's letters also go into patterns that keep their order and change the frame: the patterns (awzān) and the verb Forms I–X.
Across Ibn Fāris's dictionary. Of the 2,300 possible sets of three different sound letters (no hamza, w or y), 1,021 have at least one order as an entry. How many of their six orders are entries:
- 1 of 6319
- 2 of 6218
- 3 of 6164
- 4 of 6155
- 5 of 6107
- 6 of 658
- 1 of 6148
- 2 of 6108
- 3 of 6157
- 4 of 6179
- 5 of 6111
- 6 of 643
Of the orders al-Khalīl calls used, 2,097 are entries in Ibn Fāris and 267 are not; 17 that he calls unused are entries in Ibn Fāris.
Attested here means found in our digital texts (Ibn Fāris, Lisān al-ʿArab, Lane, the Quranic Arabic Corpus), with w and y kept apart and hamza spellings merged; it is our data, not a classical verdict.

AIClassical lexiconAl-Khalīl (al-ʿAyn) already gives both poles together: the wild/breeding sense (atān abid) and tāʾabbud, a dwelling emptied of people and taken over by wild animals.well attested
The lexicographers in chronological order, from al-Khalīl to Lane.
Al-Khalīl (al-ʿAyn) already gives both poles together: the wild/breeding sense (atān abid) and tāʾabbud, a dwelling emptied of people and taken over by wild animals. Al-Jawharī (Ṣiḥāḥ) fixes abad as dahr (time/eternity), plural ābād/ubūd, with intensified formulas like 'abad al-ābidīn' parallel to 'dahr al-dāhirīn,' while keeping tabaʾʾud as a beast's wildness. Ibn Fāris (Maqāyīs) states the governing bond explicitly: one root covers ṭūl al-mudda and tawaḥḥush, because an untouched place, left to abide without human company, reverts to wildness. Al-Rāghib (Mufradāt) sharpens the grammatical-philosophical point that abad, unlike zamān, names an undivided stretch of time and should properly resist dualization or plural, though he notes ābād as a later usage some consider postclassical. Ibn Manẓūr (Lisān) and Lane mainly consolidate this material, preserving the ḥajj-tamattuʿ ḥadīth ('li'l-abad') and Ibn Sīda's remark that 'abad al-ābidīn' is a plural of amplification rather than a true nisba plural.

Letters & soundNo entry is given for hamza in either scheme, so this letter is left without data here.speculative
What the theorists of sound symbolism would say of these letters. Speculative by nature.
No entry is given for hamza in either scheme, so this letter is left without data here. For bāʾ, al-Dabbāgh's fatḥa-gloss reads it as marking 'the utmost of might or the utmost of abasement,' and Ibn ʿArabī's Breath-correspondence assigns it to the jinn - both notions of an extremity, which a sound-symbolist might connect to abad's sense of time reaching a terminus beyond which nothing further follows. For dāl, al-Dabbāgh reads it as indicating 'something external to the self,' matching Ibn ʿArabī's assignment of dāl to the lowest heaven, which could be pressed toward the beast's tawaḥḥush - a moving outside, external to human company. This remains suggestive association only; mainstream historical linguistics does not treat individual Arabic phonemes as carrying stable independent meaning.

Root structureIbn Fāris's own permutation survey of the three letters ʾ-b-d shows four attested Arabic roots: أبد (this root, duration/wildness), أدب (gathering people to food, hence hospitality and later 'adab'), بدأ (initiating, beginning something), and دأب (settled habit, constant application);plausible

Ibn Fāris's own permutation survey of the three letters ʾ-b-d shows four attested Arabic roots: أبد (this root, duration/wildness), أدب (gathering people to food, hence hospitality and later 'adab'), بدأ (initiating, beginning something), and دأب (settled habit, constant application); بأد and دبأ are not attested. Ibn Jinnī's greater derivation (al-ishtiqāq al-akbar) would note, as a juxtaposition rather than a proven derivation, that these four permutations circle one idea-cluster: what begins (بدأ), becomes habitual (دأب), is civilized into custom (أدب), or persists altogether outside that circle, untouched (أبد).

Cognates in the sister languages, and whether the word was borrowed.
Arabic ʾ-b-d (duration, permanence) sits beside the well-attested Northwest Semitic root ʾ-b-d meaning 'to perish, be lost' (Hebrew אבד, Aramaic/Syriac ʾbd, and the related Akkadian abātu 'to destroy'); the three consonants match exactly though the sense is nearly reversed. Comparative Semitists generally treat this as one inherited root with a semantic split rather than an accidental match, the Arabic branch narrowing toward 'what remains, persists' while the West Semitic branch kept the pole of 'coming to an end.' No loanword scenario applies; this is inherited Semitic vocabulary.

Quranic exegesisAlmost all 28 Quranic occurrences are the adverb abadan closing khālidīna fīhā abadan, applied to both Paradise (4:57) and the Fire, and to the People of the Book's refusal to wish for death (2:95).plausible
How the classical exegetes read the word in the Quran.
Almost all 28 Quranic occurrences are the adverb abadan closing khālidīna fīhā abadan, applied to both Paradise (4:57) and the Fire, and to the People of the Book's refusal to wish for death (2:95). Al-Ṭabarī and al-Zamakhsharī read abadan as removing ambiguity from khālidīn, blocking any reading of eternal dwelling as merely a very long finite period. Al-Rāzī takes up the theological stakes of abadan applied to punishment in the Fire, a point of dispute in later debates over whether hell's torment is strictly unending. Al-Rāghib's lexical claim that abad denotes an undivided stretch of time (given above) is the basis exegetes use to argue that abadan intensifies rather than merely repeats khālidīn.
Philosophy & kalāmAbad is not itself a primary kalām term like wujūd, but it forms a standard technical pair with azal: azalī (without beginning) and abadī (without end) became the shorthand for describing God's eternity a parte ante and a parte post.plausible
The word as a technical term in falsafa and theology.
Abad is not itself a primary kalām term like wujūd, but it forms a standard technical pair with azal: azalī (without beginning) and abadī (without end) became the shorthand for describing God's eternity a parte ante and a parte post. Mutakallimūn used this pair to distinguish God's necessary, unconditioned eternity from the contingent temporality of created things, and later thinkers debated whether abadiyya could also properly be predicated of the soul or of Paradise/Hell.

Akbarian readingThe Faṣṣ Ādam passages pair abadī with ḥādith in describing the human being as 'the originated-eternal formation' (al-nashʾ al-dāʾim al-abadī) - a formula central to Ibn ʿArabī's claim that the Perfect Man unites the temporal pole of ḥudūth and the eternal pole of abad, which elsewhere stand opposed.well attested
The word in Ibn ʿArabī's text and terminology.
The Faṣṣ Ādam passages pair abadī with ḥādith in describing the human being as 'the originated-eternal formation' (al-nashʾ al-dāʾim al-abadī) - a formula central to Ibn ʿArabī's claim that the Perfect Man unites the temporal pole of ḥudūth and the eternal pole of abad, which elsewhere stand opposed. A second passage speaks of an 'eternal sealing' (khatman abadiyyan) placed upon the storehouse of the Hereafter, using abad to mark the finality/closure of a cosmic dispensation rather than mere endless repetition. A third passage uses abadan as an absolute negator: nothing but God's own essential necessity (al-wujūb al-dhātī) belonging to His existence can ever be grasped by unveiling and witnessing, so the Real remains, from this aspect, permanently unknown by direct tasting.
