Why this shape?What each of the 7 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.
