Why this shape?What each of the 10 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.
The grammarians on this pattern (4)
ما يكون مفعلة لازمة لها الهاء والفتحة … وذلك إذا أردت أن تكثر الشيء بالمكان، وذلك قولك: أرض مسبعة، ومأسدة
Chapter on what is mafʿala, with the -a and the a-vowel always: that is when you mean that a thing abounds in a place, as you say 'a land of many beasts of prey (masbaʿa), of many lions (maʾsada)' AI

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 lexiconNo entry from al-Khalīl or al-Rāghib is available here;well attested
The lexicographers in chronological order, from al-Khalīl to Lane.
No entry from al-Khalīl or al-Rāghib is available here; the al-Rāghib excerpt supplied belongs to ʾ-j-r. Al-Jawharī equates aḥad with wāḥid, 'the first of number' (aḥad, ithnān, aḥad ʿashar). He parses Q 112:1 as an indefinite in apposition (badal) to Allāh and notes that in negation (mā fī l-dāri aḥad) the word means 'anyone fit to be addressed'. Ibn Fāris treats the root as derived, with the hamza standing for the wāw of w-ḥ-d, and cites Ibn Durayd's mā staʾḥadtu bi-hādhā l-amr ('I did not act alone in this'). Ibn Manẓūr places al-Aḥad among the divine names: 'the Single who has never ceased to be alone, with no other beside Him'. He calls it a noun built to deny any number mentioned alongside it and repeats the w-ḥ-d derivation. Lane adds the verb aḥḥada, 'to make or declare one' (= waḥḥada), with the ḥadīth aḥḥid aḥḥid about pointing with a single finger in the testimony of faith.

Letters & soundAl-Dabbāgh's data give ḥāʾ as 'encompassing and including everything' and dāl as 'indicating something external to the self';speculative
What the theorists of sound symbolism would say of these letters. Speculative by nature.
Al-Dabbāgh's data give ḥāʾ as 'encompassing and including everything' and dāl as 'indicating something external to the self'; no meaning is supplied for the hamza. A symbolic reader might connect the all-encompassing ḥāʾ with a oneness that includes everything. Since the lexicographers regard the hamza as a replacement for wāw, a letter-by-letter reading of ʾ-ḥ-d rests on weak ground. Mainstream linguistics treats such readings as suggestive at most.

Root structureIbn Fāris gives no ʾ-ḥ chapter siblings because he files the word under w-ḥ-d.uncertain
The two-letter nucleus (Ibn Fāris's own chapters) and the permutations of the letters (Ibn Jinnī).
Ibn Fāris gives no ʾ-ḥ chapter siblings because he files the word under w-ḥ-d. The relevant comparison is therefore between aḥad and wāḥid/waḥda. Of the permutations, ḥ-d-ʾ/ḥ-d-w is 'driving (camels)', as in ḥādī, and d-ḥ-w is attested. The remaining orders are unattested. None of these gives a meaningful grouping, and greater derivation does not apply here.

Semitic kin & loanwordsThe numeral is inherited from Common Semitic *ʾaḥad- 'one'.well attested
Cognates in the sister languages, and whether the word was borrowed.
The numeral is inherited from Common Semitic *ʾaḥad- 'one'. Cognates are Hebrew ʾeḥād, Aramaic and Syriac ḥad (with the initial syllable lost), and Geʿez ʾaḥadu. Epigraphic South Arabian also has ʾḥd. Akkadian uses ištēn for 'one', but (w)ēdu 'single, sole' matches the parallel root w-ḥ-d. Comparative evidence suggests that *ʾaḥad and *waḥd were parallel forms from an early stage. The Arab grammarians' account of a hamza replacing wāw is their own internal explanation. The word is not a loanword.

Quranic exegesisMost of the 85 occurrences are the ordinary pronoun 'anyone/no one' in negation.plausible
How the classical exegetes read the word in the Quran.
Most of the 85 occurrences are the ordinary pronoun 'anyone/no one' in negation. Examples are Q 2:102 (the two angels taught no one without warning) and Q 2:96. The feminine iḥdā in Q 2:282 means 'one of the two' women witnesses. The key theological occurrence is Q 112:1. The exegetes take aḥad there as a predicate of absolute oneness. Al-Rāzī in particular discusses how aḥad differs from wāḥid: aḥad denies number and division, and in affirmative use it is applied to God alone. The grammatical point, found already in al-Jawharī, is that an indefinite can stand in apposition to a definite.
Philosophy & kalāmIn kalām, the oneness of God (aḥad/wāḥid) is the core of tawḥīd.plausible
The word as a technical term in falsafa and theology.
In kalām, the oneness of God (aḥad/wāḥid) is the core of tawḥīd. The mutakallimūn understand it as denying any partner, any likeness and any internal division. In falsafa the preferred term is usually wāḥid. Al-Kindī speaks of 'the True One' (al-wāḥid al-ḥaqq), and Avicenna argues that the Necessary Existent is one and without composition of any kind. Both authors use aḥad and aḥadiyya for this absolute, undivided unity.

Akbarian readingIn Faṣṣ Ādam aḥad occurs only as the indefinite 'anyone' (the relevant passage is on the nafs wāḥida).plausible
The word in Ibn ʿArabī's text and terminology.
In Faṣṣ Ādam aḥad occurs only as the indefinite 'anyone' (the relevant passage is on the nafs wāḥida). Its uses are nonetheless pointed. No one dares open the treasuries while the king's seal is on them. No one knows anything of the Real except what his own essence gives him. And although the Real is present in every existent according to its reality, 'no one has the totality that belongs to the vicegerent'. More broadly, Ibn ʿArabī's terminology distinguishes aḥadiyya, the unity of the Essence without relations, from wāḥidiyya, the unity of the names with their multiplicity. No Iṣṭilāḥ definition for aḥad is supplied here.
Draws on: Fuṣūṣ, Faṣṣ Ādam · aḥadiyya vs wāḥidiyya
