Arabic Verb Forms I to X Explained, With Qur'an Examples

Arabic verb forms are ten standard patterns, numbered I to X, that turn one three-letter root into a family of related verbs. Each pattern adds letters or vowels to the root and nudges the meaning in a predictable direction: causing something, doing it with someone, doing it to yourself, or asking for it. Form I is the base.

You already recite some of them in every rakʿah. In the ayah below, نَعْبُدُ (naʿbudu, we worship) is Form I of ع-ب-د, the plain action. نَسْتَعِينُ (nastaʿīnu) comes from ع-و-ن, the root of help, and the added letters س and ت turn 'help' into 'ask for help': Form X. This guide gives you all ten forms in one table with a checked Qur'anic example each, their verbal nouns and participles, and a method for naming the form of any verb in your mushaf. If roots are new to you, read how the Arabic root system works first.

What are the 10 Arabic verb forms?

The 10 Arabic verb forms are fixed templates, written on the model root ف-ع-ل (f-ʿ-l, to do), into which a root is placed to make a new verb. Arabic grammarians call each template a wazn (plural awzān), a measure, and name it by its shape: the istafʿala pattern, the tafāʿala pattern. The Roman numerals I to X are a Western convention from dictionaries such as Hans Wehr, which is why you will also see them called Arabic verb forms 1-10.

Form I is the bare verb (al-mujarrad): the three root letters and their vowels. Forms II to X are augmented (al-mazīd): the same root with one, two or three letters added before, inside or around it. Each is a verb (fiʿl), one of the three building blocks of Arabic. Here are all ten:

What does each Arabic verb form mean?

Each Arabic verb form adds a typical layer of meaning to its root, and the forms are easiest to learn in pairs that behave alike. Treat these meanings as strong tendencies, not laws; the dictionary has the final word on any verb. Form I carries the plain meaning of the root: خَلَقَ (khalaqa) is 'He created', from خ-ل-ق. It is also the only form whose vowels you cannot predict. The past can be faʿala, faʿila or faʿula, and the present-tense vowel changes from verb to verb: فَتَحَ يَفْتَحُ (he opened, he opens), but عَلِمَ يَعْلَمُ (he knew, he knows). Learn every Form I verb as a past and present pair.

Form II and Form IV: making something happen

Form II doubles the middle root letter and Form IV adds a hamza in front, and both often make a verb causative. From ع-ل-م, Form I عَلِمَ is 'he knew' while Form II عَلَّمَ is 'he taught', literally he caused someone to know. Form II can also show intensity or repetition. From ن-ز-ل, Form IV is 'to send down', as in Surah al-Qadr. In al-Fātiḥah, أَنْعَمْتَ (You bestowed favour) is Form IV of ن-ع-م. The very common ءَامَنُوا۟ (they believed, 3:102) is Form IV of أ-م-ن, where the added hamza meets the root's own hamza and is written as one long ءَا.

Form III and Form VI: you and someone else

Form III lengthens the vowel after the first root letter and usually means doing the action with or towards another person, often with effort: جَـٰهَدُوا۟ (jāhadū) is 'they strove', and قَاتَلَ is to fight against someone. Form VI adds a ت to Form III and makes the action mutual: لِتَعَارَفُوٓا۟ in 49:13, from ع-ر-ف, is 'that you may know one another'.

Form V and Form VII: what happens to the doer

Form V adds ت to Form II and turns the action back on the doer: if عَلَّمَ is 'he taught', تَعَلَّمَ is 'he learned'. In An-Nisa 4:82 Allah asks why people do not يَتَدَبَّرُونَ the Qur'an, Form V of د-ب-ر, to reflect on it carefully. Form VII adds اِن in front and describes something happening to the subject, usually without naming who did it. Surah al-Infiṭār opens with ٱنفَطَرَتْ, 'the sky breaks apart', Form VII of ف-ط-ر, and the surah's name is that verb's verbal noun.

Form VIII: the form that changes shape

Form VIII slips a ت in after the first root letter and often means doing something for or to yourself, though its sense drifts from the root more than most. ٱقْتَرَبَتِ, from ق-ر-ب (near), means 'it has drawn near', and in this ayah Form VIII and Form VII sit side by side:

Form VIII is the form most likely to fool you, because its ت changes to suit the first root letter. After ص, ض, ط or ظ it becomes ط: ٱصْطَفَىٰٓ (iṣṭafā), 'He chose' (3:33), from ص-ف-و. After ز it becomes د. And when a root begins with و, the و merges into the ت:

Form IX and Form X: colours, and asking

Form IX doubles the last root letter and is kept almost entirely for colours and physical states. It is rare, and one ayah teaches it: تَبْيَضُّ (turn white) is Form IX of ب-ي-ض, and وَتَسْوَدُّ (turn black) is Form IX of س-و-د.

Form X adds اِسْتَ in front and most often means seeking or asking for what the root means. غَفَرَ is 'he forgave'; ٱسْتَغْفِرُوا۟ in 71:10 is 'ask forgiveness'. Form X can also mean considering something to be a certain way, and sometimes it describes a settled state, as in ٱلْمُسْتَقِيمَ, the path that is straight and upright, from ق-و-م.

How do you identify an Arabic verb form?

You identify an Arabic verb form by removing everything that marks tense and person, then comparing what is left with the three root letters. Whatever has been added to the root tells you the form:

What are the verbal noun and participle of each form?

Every derived verb form also produces nouns on fixed patterns, so the forms teach you many Qur'anic nouns too. The verbal noun (maṣdar) names the action, and the active participle (ism fāʿil) names the one doing it. In Forms II to X the active participle begins with مُ: مُّسْلِمُونَ (Muslims) is Form IV and ٱلْمُسْتَقِيمَ is Form X. It is the present-tense pattern with مُ in place of the prefix, except that Forms V and VI turn the fatha before the last letter into a kasra (يَتَعَلَّمُ, مُتَعَلِّم).

One root, four forms: ن-ز-ل in the Qur'an

Following one root through its forms is the clearest way to see the system at work. The root ن-ز-ل carries the idea of coming down, and the Qur'an uses it in at least four verb forms. Why an ayah uses one form rather than another is a question for the books of tafsir; for now, naming each form is already real progress.

Common mistakes when learning Arabic verb patterns

Most mistakes with Arabic verb patterns come from treating them as a maths formula instead of a reading aid. These habits keep you accurate:

How should a beginner practise the verb forms?

The best way to practise the Arabic verb forms is to label real words in surahs you already recite, a few minutes a day. Verb forms belong to ṣarf (morphology); if you are unsure where that sits in your studies, see the difference between sarf and nahw.
