Arabic Verb Forms (الأوزان) Explained — Forms I–X with Examples

Every Arabic verb is built on a root — usually three consonants — poured into one of ten common molds called أوزان (awzān, "patterns" or "forms"). Learn the ten molds once and you can read thousands of verbs you have never seen, because the mold tells you both the pronunciation and half the meaning.

The ten forms at a glance

The table uses the demonstration root ف-ع-ل the way Arab grammarians always have. The مضارع (present) column matters as much as the past: it is how you recognize the form mid-sentence.

Form Past (الماضي) Present (المضارع) Typical meaning shift
I فَعَلَ يَفْعُلُ / يَفْعِلُ / يَفْعَلُ the base meaning
II فَعَّلَ يُفَعِّلُ intensive or causative — to make someone do it
III فَاعَلَ يُفَاعِلُ doing it to/with someone
IV أَفْعَلَ يُفْعِلُ causative — to cause it to happen
V تَفَعَّلَ يَتَفَعَّلُ reflexive of II — to have it done to oneself
VI تَفَاعَلَ يَتَفَاعَلُ mutual — doing it to each other
VII اِنْفَعَلَ يَنْفَعِلُ passive-like — to become done
VIII اِفْتَعَلَ يَفْتَعِلُ reflexive/middle — to do for oneself
IX اِفْعَلَّ يَفْعَلُّ colors and defects only
X اِسْتَفْعَلَ يَسْتَفْعِلُ seeking or considering — to ask for it

One root, many verbs

Watch the root ع-ل-م ("knowing") move through the molds:

  • عَلِمَ (I) — he knew
  • عَلَّمَ (II) — he taught (caused someone to know)
  • تَعَلَّمَ (V) — he learned (had himself taught)
  • اِسْتَعْلَمَ (X) — he inquired (sought to know)

Or خ-ر-ج ("exiting"):

  • خَرَجَ (I) — he went out
  • أَخْرَجَ (IV) — he brought something out
  • اِسْتَخْرَجَ (X) — he extracted

The dictionary form is always the third-person masculine singular past — Arabic has no infinitive, so "to write" is listed as كَتَبَ, literally "he wrote."

How to recognize a form in the wild

Three quick tells cover most cases:

  1. A doubled middle letter (shadda) in the past means Form II: دَرَّسَ "to teach."
  2. A leading اِ with a ت inside means Form VIII: اِجْتَمَعَ "to gather." Watch for the assimilations — after ص، ض، ط، ظ the ت becomes ط (اِصْطَبَرَ), and after ز، د، ذ it becomes د (اِزْدَحَمَ).
  3. A leading اِسْتَـ means Form X: اِسْتَقْبَلَ "to receive."

The forms that trip learners most are V and VI in the present tense, because the doubled letter and the long alif hide behind the يَتَـ prefix. Reading fully vocalized text for a few weeks fixes this faster than drilling tables.

Where to practice

Every page in the Illuminated Arabic Reader library shows a verb table with the الماضي، المضارع، الأمر and المصدر of each verb on the page — form-correct, never reduced to a simpler form. Good starting points:
