If you’ve ever tried to tell someone “write!” or “go!” in Arabic and ended up guessing at the ending, you’ve run into the imperative — one of the trickiest verb forms for learners because it changes shape depending on the verb itself.
The imperative in Arabic, known as فعل الأمر, isn’t a random exception list to memorize. It follows a small set of derivation rules that, once you see the logic, apply to almost any verb you’ll ever use.
By the end, you’ll be able to look at a present-tense Arabic verb and derive its command form yourself, instead of relying on memorized examples.

What Is the Imperative in Arabic?
The imperative in Arabic, or فعل الأمر, is the verb form used to instruct, request, or command that an action take place.
Its meaning is future-oriented: a command always points to an action that hasn’t happened yet, which is exactly why Arabic grammar derives the imperative from the present tense (الفعل المضارع) rather than the past tense.
This connection between the imperative and the present tense is the single most useful thing to understand before memorizing any rule.
The present tense in Arabic is the form associated with the future and the ongoing, and a command is, by definition, asking for something to happen in the future.
So Arabic doesn’t treat the imperative as a separate, unrelated verb shape — it treats it as a present-tense verb with its marker letter removed.
Why You Need to Start From the Present Tense, Not the Dictionary Form
Many learners try to form the imperative by changing the past tense or guessing from the verb’s root.
That approach fails constantly, because the imperative’s entire derivation depends on what’s left over after you strip the present-tense marker letter (أ ، ن ، ي ، ت) from the front of the verb.
Once that letter is gone, what happens next depends entirely on the letter that’s left exposed.

How Is the Imperative Verb Formed in Arabic?
To form the Arabic imperative, you drop the present-tense marker letter from the front of the verb, then handle whatever letter is now exposed at the start.
What you do with that exposed letter depends on whether it can be pronounced on its own.
Step 1: Strip the Present-Tense Marker
Every present-tense Arabic verb opens with one of four marker letters: أ، ن، ي، ت. Removing this letter is always the first move, regardless of the verb type.
Step 2: Check What’s Left at the Front
Once the marker is gone, the letter now sitting at the start of the verb is either movable (carries a vowel) or sākin (carries no vowel — silent). This single check decides which rule applies next.
Rule A: If the Exposed Letter Already Carries a Vowel, Keep It As-Is
If the letter left after removing the marker already has a vowel sound on it, no further change is needed — the imperative is simply that remaining shape.
| Present-tense form (with ت‑) | After removing ت‑ (exposed letter) | Imperative form | Meaning |
| تَدَحْرَجَ (tadahrāja) | دَحْرَجَ (dahraja) — دَ has fatha | دَحْرِجْ (dahrij) | Roll! |
| تَرُدُّ (taruddu) | رُدُّ (rudu) — رُ has damma | رُدَّ (rudd) | Return! |
| تَقُومُ (taqūmu) | قُومُ (qūmu) — قُ has damma | قُمْ (qum) | Stand up! |
| تُبَادِلُ (tubādilu) | بَادِلُ (bācilu) — بَ has fatha | بَادِلْ (bādil) | Exchange! |
| تُوَصِّلُ (tuwassilu) | وَصِّلُ (wassilu) — وَ has fatha | وَصِّلْ (wassil) | Deliver! / Connect! |
Rule B: If the Exposed Letter Is Sākin, Add a Hamzat al-Waṣl
Arabic cannot pronounce a word that opens with a silent, vowel-less consonant — so when stripping the marker letter leaves a sākin letter exposed, a hamzat al-waṣl (همزة الوصل) is added to the front to make the word pronounceable.
This connecting hamza is not part of the verb’s root; it exists purely to carry a starting vowel. By default, this hamza carries kasra.
Example: from يَعْلَمُ (he knows) comes اِعْلَمْ (know!) — the ع was left sākin, so a kasra-bearing hamza was added.
| Present-tense form (with ت‑) | After removing ت‑ (exposed letter) | Imperative form (with hamzat al-waṣl) | Meaning |
| تَعْلَمُ (taʿlamu) | عْلَمُ (ʿlamu) — ع is sākin | اِعْلَمْ (iʿlam) | Know! |
| تَكْتَبُ (taktabu) | كْتَبُ (ktabu) — ك is sākin | اكْتُبْ (uktub)* | Write! |
| تَسْتَقِرُّ (tastaqirru) | سْتَقِرُّ (staqirru) — س is sākin | اسْتَقِرَّ (istaqir) | Settle! |
| تَسْتَمِعُ (tastamiʿu) | سْتَمِعُ (stamiʿu) — س is sākin | اسْتَمِعْ (istamiʿ) | Listen! |
| تُعْطِي (tuʿṭī) | عْطِي (ʿṭī) — ع is sākin | اَعْطِ (aʿṭi) | Give! |
Exception — when the hamza takes ḑamma instead
If the third root letter of the verb carries ḑamma in the present tense, the hamzat al-waṣl matches it and takes ḑamma too, for vowel harmony across the word.
Example: from يَخْرُجُ (he exits) comes اُخْرُجْ (exit!) — the ر carries ḑamma, so the connecting hamza takes ḑamma as well, not the default kasra.
Practitioner note
This ḑamma exception is the rule most learners forget entirely, because the kasra default is taught first and repeated more often.
The fix is mechanical, not memorization-based: check the vowel on the final root letter in the present tense before deciding the hamza’s vowel. If it’s ḑamma, match it. Otherwise, default to kasra.

Verbs built on the أفْعَلَ pattern — such as أكْرَمَ (he honored) and أخْرَجَ (he removed) — behave differently from Rule B.
Their imperative doesn’t use a connecting hamzat al-waṣl at all; it uses a hamzat al-qaṭ’ (a “true” hamza that’s part of the word itself), and that hamza always carries fatḥa, regardless of the vowel on the final root letter.
| Present‑tense form (with ت‑) | After removing ت‑ (exposed letter) | Imperative form (hamzat al‑qaṭ‘ with fatḥa) | Meaning |
| تَأْكَرَمُ (taʾkaramu)* — derived from أَكْرَمَ | أَكْرَمَ (akrama) — initial hamza part of root | أَكْرِمْ (akrim) | Honor! |
| تَأْخْرِجُ (taʾkhriju)* — derived from أَخْرَجَ | أَخْرَجَ (akhraja) — initial hamza part of root | أَخْرِجْ (akhrij) | Take out! |
| أَفْهَمُ → (present: يُفْهِمُ / تَفْهَمُ) | أَفْهَمَ (afhama) | أَفْهِمْ (afhim) | Make understand! |
| أَسْلَمُ → (present: يُسْلِمُ / تَسْلِمُ) | أَسْلَمَ (aslama) | أَسْلِمْ (aslim) | Submit! |
This is a frequent point of confusion because أَكْرِمْ visually resembles the hamzat al-waṣl forms from Rule B.
The distinguishing test: if the verb’s present tense begins with a marker hamza followed by a pattern that traces back to أفْعَلَ, the resulting imperative hamza is fixed at fatḥa — it never shifts to kasra or ḑamma the way a hamzat al-waṣl does.

How Do Verb Types (Regular, Weak, Doubled) Affect The Imperative Form?
The core process above — strip the marker, then apply Rule A, B, or C — applies to every Arabic verb. What changes across verb types is simply which letter ends up exposed once the marker is removed, not the underlying logic.
- For a sound verb with no weak letters, the second root letter is what’s typically exposed, and it’s usually sākin, which triggers Rule B and the hamzat al-waṣl — as seen with اِعْلَمْ and اُخْرُجْ above.
- For a doubled verb like تَرُدُّ, the exposed letter already carries a vowel because of the assimilation between the two identical root letters, which is why رُدَّ follows Rule A directly with no hamza needed.
Weak verbs (those containing و، ا، or ي in the root) often lose that weak letter entirely once the imperative is formed, since the jussim-style ending that governs the imperative typically strips it.
This is a separate behavior from the hamza rules above, and it’s worth treating as its own checkpoint rather than folding it into Rules A–C.
What Are the Most Common Mistakes in Forming the Arabic Imperative?
Three errors account for the bulk of mistakes when students derive the Arabic imperative.
- The first is defaulting to kasra on every hamzat al-waṣl without checking the final root letter’s vowel — producing اِخْرُجْ instead of the correct اُخْرُجْ.
- The second is confusing Rule B (hamzat al-waṣl, connecting) with Rule C (hamzat al-qaṭ’, fixed at fatḥa) for أفْعَلَ-pattern verbs, which leads to writing اِكْرِمْ instead of أَكْرِمْ.
- The third is forgetting that the entire derivation starts from the present tense, not the past tense or the root in isolation — attempting to derive the imperative from دَحْرَجَ (past tense) instead of تَدَحْرَجَ (present tense) produces the wrong exposed letter and the wrong form.
Catching these patterns reliably takes repetition with feedback — a written rule is easy to misapply the first few times you try it live in speech.
A Recommended Approach: Master the Imperative Through Live Correction
Reading the derivation steps is one thing. Applying them instantly while speaking is another — and that gap is exactly where most self-taught learners stall.
A structured course where an instructor hears you form the imperative out loud and corrects the rule the moment you misapply it closes that gap far faster than working through written tables alone.
This is exactly the structure used in Kalimah Center’s Arabic grammar courses, where one-on-one sessions focus on hearing how you build commands and fixing the rule application in real time rather than after weeks of repeated practice.

Book Your Free TrialConclusion
The imperative in Arabic is derived directly from the present tense by removing the marker letter at the front of the verb, then handling whatever letter is left exposed.
A movable letter stays as it is; a sākin letter triggers a hamzat al-waṣl, which defaults to kasra but shifts to ḑamma when the verb’s final root letter carries ḑamma; and verbs from the أفْعَلَ pattern use a fixed, fatḥa-bearing hamzat al-qaṭ’ instead.
The real takeaway is that the Arabic imperative isn’t a memorization exercise — it’s a derivation process with three checkpoints.
Once you can identify which checkpoint a verb falls into, forming the imperative in Arabic becomes a quick mechanical check rather than a guessing game, and steady, corrected practice is what turns that check into instinct.
FAQs
What is the imperative in Arabic grammar?
The imperative in Arabic grammar, فعل الأمر, is the verb form used to command or request an action.
It is derived from the present-tense verb by removing the present-tense marker letter, because the meaning of a command — something not yet done — aligns with the future-oriented present tense rather than the past.
What is an imperative sentence in Arabic?
An imperative sentence in Arabic is built around a command verb, such as اُخْرُجْ مِنَ الغُرفةِ (leave the room!).
These sentences typically open directly with the imperative verb, since the subject (“you”) is understood and doesn’t need a separate pronoun.
What does imperative mean in simple terms?
Imperative means “expressing a command or instruction.” In Arabic grammar, this concept is captured by فعل الأمر, a verb form whose entire function is to request that an action happen, rather than describe one that has already occurred.
What is the Arabic imperative grammar rule in one sentence?
The Arabic imperative grammar rule is: remove the present-tense marker letter, and if a sākin letter is left exposed at the front, add a hamzat al-waṣl (usually kasra, but ḑamma if the verb’s final root letter carries ḑamma); أفْعَلَ-pattern verbs instead take a fixed hamzat al-qaṭ’ with fatḥa.
Is there a full list of Arabic imperative verbs to memorize?
Rather than memorizing a fixed arabic imperative verbs list, it’s more reliable to learn the three-step derivation process — strip the marker letter, then apply the correct rule for the exposed letter — because this step can produce the correct imperative form for most verbs, including ones you haven’t encountered before.
Why do some Arabic imperative verbs start with a hamza and others don’t?
Some imperative verbs start with a hamzat al-waṣl, a connecting hamza added only because Arabic can’t pronounce a sākin letter at the start of a word; this hamza isn’t part of the root.
Verbs from the أفْعَلَ pattern instead start with a hamzat al-qaṭ’, a true root hamza fixed at fatḥa — the two look similar but follow different rules.
