Why this shape?What each of the 6 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

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.

The lexicographers in chronological order, from al-Khalīl to Lane.
Al-Khalīl (al-ʿAyn) treats bāb as a known, simple word, notes the denominative verb tabwīb, and records bawwāb 'doorkeeper, chamberlain' along with the toponyms Bāb al-Abwāb and al-Bābah, a frontier town of the Byzantines. Al-Jawharī (al-Ṣiḥāḥ) gives the regular plural abwāb and the rare paired form abūbah, used only alongside akhbiyah for metrical matching in Ibn Muqbil's verse and not usable alone; he records tabawwaba bawwāban 'to take on a doorkeeper', abwāb mubawwabah 'classified into chapters, like aṣnāf muṣannafah', and the idiom min bābatik, 'suited to you'. Ibn Fāris (Maqāyīs) reduces the root to a single sense — tabawwatu bawwāban, 'to take a gatekeeper' — and notes that bāb's alif goes back to a wāw, distinguishing it from the toponym al-Bawbāh, a waystation between Najd and al-Ṭāʾif, probably a separate word. Ibn Manẓūr (Lisān al-ʿArab) preserves the same al-bawbāh, glossed as a desert or wasteland (= al-mawmāh), the plurals abwāb and bībān, and the debate, via Ibn al-Aʿrābī and al-Liḥyānī, over whether abūbah is truly a broken plural of bāb, which is anomalous since a faʿl-pattern noun does not normally break this way.

Letters & soundThe akbarī tradition and al-Dabbāgh give bāʾ as the jinn, and 'an indication of a thing at the utmost of might or the utmost of abasement';speculative
What the theorists of sound symbolism would say of these letters. Speculative by nature.
The akbarī tradition and al-Dabbāgh give bāʾ as the jinn, and 'an indication of a thing at the utmost of might or the utmost of abasement'; wāw as 'the determination of ranks, stations and waystations' and, for al-Dabbāgh, 'the intertwined things in the human being, such as veins and fingers'. Read speculatively, a door — bāb — doubled in bāʾ and framed by wāw could be heard as precisely a threshold between stations, wāw marking the waystation and bāʾ marking the extremity of might or abasement that lies on either side of it. This is squarely within Ibn ʿArabī's and al-Dabbāgh's letter-symbolism and is not endorsed by mainstream philology, which finds no controlled evidence for such readings.

Root structureNo two-letter nucleus siblings for و-ب-ب are supplied in the sources given, so Ibn Fāris's chapter for this root cannot be situated among neighboring roots here;uncertain
The two-letter nucleus (Ibn Fāris's own chapters) and the permutations of the letters (Ibn Jinnī).
No two-letter nucleus siblings for و-ب-ب are supplied in the sources given, so Ibn Fāris's chapter for this root cannot be situated among neighboring roots here; Maqāyīs simply states the root's single sense as 'taking on a gatekeeper', with bāb's alif derived from an original wāw. Among the permutations, ب-و-ب alone is productive (27 Qurʾānic occurrences); و-ب-ب is marked attested but without a recorded sense in the material given, and ب-ب-و is unattested. The word's shape — a weak medial radical reducible to a geminated biliteral ب-ب — fits the pattern of primitive biliteral Semitic nouns more readily than a fully triliteral derivation (see the semitic lens below), though this is a structural observation, not an etymological claim.

Semitic kin & loanwordsArabic bāb has a strong, well-attested Semitic cognate set: Akkadian bābu, 'gate, door' (whence Bāb-ili, 'gate of the god', behind the name 'Babylon'), and Aramaic/Syriac bābā, both meaning 'door, gate', closely matching Arabic bāb in form and sense.well attested
Cognates in the sister languages, and whether the word was borrowed.
Arabic bāb has a strong, well-attested Semitic cognate set: Akkadian bābu, 'gate, door' (whence Bāb-ili, 'gate of the god', behind the name 'Babylon'), and Aramaic/Syriac bābā, both meaning 'door, gate', closely matching Arabic bāb in form and sense. No confident Hebrew cognate of comparable directness is identifiable, since Hebrew's ordinary words for door are petaḥ and delet, though Hebrew preserves the root indirectly in the loanword Bāvel. Given this pan-Semitic spread and the word's primitive biliteral shape, this looks like an inherited common Semitic 'gate' word rather than a specific loan into Arabic from any one neighbor; if any directional borrowing occurred it would most plausibly run through Aramaic, given its role as a contact language, but the evidence here does not establish this with confidence.

The abwāb of 2:189, 'come to houses through their doors', are read by al-Ṭabarī as correcting a pre-Islamic pilgrim custom of entering houses through the back during iḥrām, and by al-Zamakhsharī and al-Rāzī as sliding into a general proverb: approach matters through their proper, sanctioned channel, not by illegitimate shortcuts. Across both verses the exegetes keep the literal architectural sense in view while letting it carry a moral or legal lesson about correct approach.

Akbarian readingAt the opening of the Faṣṣ Ādam, Ibn ʿArabī names the entire chapter a bāb — 'a divine wisdom in an Adamic word, and this is this bāb' — using the term in its ordinary sense of a 'chapter' or 'gate' of wisdom opened for the reader, parallel to the following faṣṣ, called a bāb nafthī in a Sethian word.plausible

The usage is structural rather than technical: each Faṣṣ is conceived as a door through which a particular prophetic wisdom is entered, consistent with bāb's root sense of an opening set up for passage.
