Alternative Questions: mI … mI, yoksa

An alternative question offers the listener a closed set of choices and asks them to pick: "Tea or coffee?", "Are you coming or staying?" English builds these with the plain word or, the same word it uses to list options in a statement. Turkish does not. It marks each option with the question particle mI — Çay mı kahve mi? — or links two complete questions with the special connector yoksa "or (else)." The everyday listing word veya "or" is wrong here, and reaching for it is the single most reliable English-speaker mistake on this whole topic. Once you see why veya is wrong, the right pattern falls into place.

The core idea: each option is its own little question

A yes/no question puts one mI in the sentence and asks "is this true — yes or no?" An alternative question is really two (or more) yes/no questions fused together: "Is it A? Is it B?" Because each option is being questioned, each option gets its own mI. You are not listing A and B with a conjunction; you are interrogating each one in turn and inviting the listener to confirm whichever is true.

Hear the logic in the literal reading: Çay mı kahve mi is "Tea? Coffee?" — two miniature questions side by side. There is no word for "or" anywhere in it. The repeated mI is the "or." This is why a learner who writes Çay veya kahve? sounds, to a Turkish ear, like they are reading a menu line aloud rather than asking someone to choose.

Noun-choice alternatives: A mI B mI?

When the choice is between two things — two nouns, two phrases — line them up and stamp each with a harmonizing mI. The particle harmonizes to the vowel right before it (mı / mi / mu / mü), so the two particles in one question can differ.

Notice that the options can be more than bare nouns — dışarıda "outside" vs evde "at home", otobüsle "by bus" vs taksiyle "by taxi" — and each still takes its own mI. Whatever case or postposition the option carries, the mI lands after it: otobüsle mi, taksiyle mi. The rest of the sentence (here gidelim "shall we go") is shared by both options and stated once, at the end.

You can extend the pattern to three or more options simply by tagging each with mI:

Verb-choice alternatives: full predicate mI … (yoksa) … mI?

When the choice is between two actions, each action is a full verbal predicate, and each takes the yes/no-question form you already know from forming yes/no questions. So you build two complete verb-questions and set them next to each other. In these longer, two-predicate questions it is very common — and clearer — to drop in yoksa "or (else)" between them.

Each verb keeps its own complete question marking — geliyor musun? "are you coming?" and kalıyor musun? "are you staying?" — and yoksa sits at the seam between them. You could technically say Geliyor musun, kalıyor musun? without yoksa and still be understood, but with two full predicates yoksa is the natural, idiomatic choice; it signals "or, alternatively" and stops the two questions from sounding like a rushed double-question.

The crucial contrast: yoksa vs veya

This is the heart of the page. Turkish keeps two jobs strictly separate that English lumps under one word or:

The same two options — et "meat" and balık "fish" — take veya when you are merely listing them as acceptable, and mI … mI (or yoksa) when you are asking the listener to choose. If you transplant veya into the question (Et veya balık mı alalım?), the result is at best clumsy and at worst changes the meaning, because veya bundles the two into a single lumped "meat-or-fish" that the lone mI then questions as one unit — "shall we get [meat-or-fish]?" — losing the either/or force.

"… or not?": the negated alternative

A very common alternative question pits an action against its own negation: "Are you coming or not?" English can shorten this to a tag-like "…or not?", but Turkish prefers to spell out the second, negative predicate in full, again joined by yoksa.

When you want to embed this "whether or not" question inside a larger sentence — "I don't know whether you're coming or not" — you switch to the embedded-question machinery, nominalizing the verb with -DIK: gelip gelmediğini "whether (you) come or not."

That gelip gelmediğini pattern — affirmative converb gel-ip + negative participle gelme-diğini — is the standard way to fold an "A-or-not" choice into a statement, and it is worth memorizing as a fixed frame.

Common mistakes

This is the headline error. The listing word veya cannot build a choice question. Mark each option with its own mI: Çay mı kahve mi?

Between two full questions the connector is yoksa, and each verb must keep its own mI. Both halves are questions, so both carry the particle.

For three options in a choice question, simply tag all three with mI. Mixing in ya da / veya breaks the parallel choice structure.

The mI marks the option, but it does not replace the case or postposition. Since gitmek "to go" takes the instrumental for means of transport, both options need -le/-yle before the mI: otobüsle mi, taksiyle mi.

Turkish does not tack on a bare "…or not." Spell out the negative predicate as its own question — gelmiyor musun? — joined by yoksa.

Key takeaways

• An alternative question marks each option with its own mI — Çay mı kahve mi? — and the repeated mI is the "or."
• For two full verb-questions, link them with yoksa "or (else)": Geliyor musun yoksa kalıyor musun?
• Never use veya / ya da in a choice question — those are statement-list words: Çay veya kahve içerim (statement) vs Çay mı kahve mi içersin? (question).
• The options keep whatever case or postposition the predicate needs, with mI added after: otobüsle mi taksiyle mi.
• "A or not?" is a full negated question — gelmiyor musun? — and, when embedded, becomes the nominalized gelip gelmediğini "whether (you) come or not."
