كيف

The word كيف serves two primary functions in Arabic:

• Asking about Manner: It inquires about the method or means by which an action is performed. For example, 'كيف وصلت؟' (How did you arrive?).
• Asking about Condition: It inquires about the state or health of a subject. The most famous example is كيف حالك؟ (How are you?).

Grammatical Rules:
1. Sentence Position: Like most question words, it normally heads its interrogative clause; a conjunction or introductory clause may precede it.
2. Word Class: Arabic grammarians classify كيف as a noun (ism). This allows it to function as a predicate (khabar) or a circumstantial adverb (ḥāl).
3. With Linking Verbs: When used with was/were, it functions as the predicate of the verb (Khabar Kāna), as in 'كيف كان الامتحان؟' (How was the exam?).
4. Conditional Form: By adding the suffix '-mā', it becomes kayfamā (in whatever way), which is used to start conditional sentences.
5. Register: While كيف is the formal standard, you will hear variations in everyday speech.

Important Distinction: Do not use كيف to ask about quantity (e.g., 'How many'). For those, you must use كم.

Beyond a Literal Question: كَيْفَ لَا؟ can express “Of course!” in response to a suggestion, and كَيْفَ تَجْرُؤُ! means “How dare you!” The context makes these rhetorical rather than requests for a method. In everyday speech, Egyptian commonly uses إزّاي (izzāy), while Levantine commonly uses كيف (kīf), without the final standard-Arabic vowel.

Conditional Extension: كيفما connects a condition and its result: كَيْفَمَا تَجْلِسْ أَجْلِسْ means “However you sit, I will sit.” Both present verbs are jussive in this common teaching pattern. Classical grammarians differ over whether كيفما itself governs the jussive, so this should not be confused with an uncontested rule about ordinary interrogative كيف.
