Hindi question words: क्या, कौन, कहाँ, कब, क्यों and कैसे

Hindi has six question words to learn first: क्या (what), कौन (who), कहाँ (where), कब (when), क्यों (why) and कैसे (how). Unlike English, they do not move to the front of the sentence — they sit exactly where the answer would sit, immediately before the verb. आप कहाँ जा रहे हैं? is “you where going are?”. And क्या is two different words depending on its position: at the front it turns a statement into a yes-or-no question, and before the verb it means “what”.

That second point is the one worth reading twice. आपका नाम क्या है? means “what is your name?”. क्या आपका नाम है? is a different question entirely, and not one you meant to ask.

The six question words

They stay in place instead of moving to the front

English pulls its question word to the start of the sentence and rearranges everything behind it: “where are you going?” English moves “where”, then inverts “you are” into “are you”. Hindi does neither. The question word simply occupies the slot the answer would have occupied, and the rest of the sentence is untouched.

The verb still lands at the end, exactly as it does in a statement — the rule covered in why the verb always goes last. A Hindi question is a Hindi statement with one word swapped out.

क्या does two jobs, and position decides which

This is the single most useful thing on this page. When क्या stands at the very beginning of the sentence, it is not asking “what” — it is a marker that turns the whole sentence into a yes-or-no question, and it translates to nothing at all.

Both sentences contain the identical four words. Moving क्या from the front to the pre-verb slot changes the question from “do you speak Hindi” to “what do you speak”.

In speech the front क्या is often dropped and rising intonation does the work instead — आप हिंदी बोलते हैं? with the pitch lifted at the end is a perfectly normal yes-or-no question. In writing, keep the क्या.

कौन changes shape when a postposition follows

कौन is the only one of the six that has other forms, and it does not look much like its base. The forms are built from किस rather than कौन.

किसने is कौन carrying the ने marker, which is required whenever the verb is transitive and in the past tense — यह किसने किया? not यह कौन किया?. That marker and the shape-change in front of it are the subject of Hindi postpositions.

कैसा, कितना and कौन सा agree like adjectives

Three question words are adjectives rather than fixed words, so they change ending to match the noun they ask about.

This is why आप कैसे हैं? is addressed to a man and आप कैसी हैं? to a woman — the question word is agreeing with the person being asked, on the same gender pattern described in every Hindi noun has a gender. कैसे, without agreement, is the separate adverb meaning “by what means”: यह कैसे हुआ?

Answering, and the जी that softens it

• हाँ (yes) and नहीं (no) are the bare answers, and bare is slightly blunt with anyone senior.
• जी हाँ and जी नहीं are the polite versions, and जी on its own works as a respectful yes — see the Hindi words that carry respect.
• To negate the question itself, नहीं goes immediately before the verb: क्या आप नहीं जाएँगे? — “are you not going?”

Why translation tools get this wrong

The क्या ambiguity is the failure to watch for. An engine that puts क्या in the wrong slot produces a grammatical sentence asking something you did not ask.

Row one is the common one, and it is worth recognising on sight, because “क्या आपका नाम है?” reads as a yes-or-no question about whether something is your name. Row three is not wrong so much as foreign — it is English word order wearing Hindi words, the pattern described in why translation tools fail at Hinglish.

A quick self-check before sending anything: if your sentence starts with क्या, you are asking a yes-or-no question. If you meant to ask “what”, क्या belongs later, just before the verb.

The short version

• Question words go where the answer would go, immediately before the verb — not at the front.
• Nothing else in the sentence moves, and the verb still ends it.
• क्या at the front = a yes-or-no marker that translates to nothing.
• क्या before the verb = “what”.
• कौन becomes किसे, किसका, किससे and किसने once a postposition is involved.
• कैसा, कितना and कौन सा agree with the noun; कैसे is the adverb.
• जी हाँ and जी नहीं are the polite answers.
