To ask someone directly about their feelings, states, or professions, attach personal "to be" endings (like "I" or "you") directly to the yes/no question particle.
The personal ending will always harmonize with the vowel of the question particle (mı, mi, mu, or mü).
Asking "Are you...?" (Sen)
To ask a single person "Are you...?" informally, attach the second-person singular suffix (-sın, -sin, -sun, -sün) to the question particle.
- a / ı → mısın
- e / i → misin
- o / u → musun
- ö / ü → müsün
Asking "Am I...?" (Ben)
When adding the first-person singular suffix (-ım, -im, -um, -üm) to the question particle, you must insert the buffer letter y to prevent two vowels from bumping into each other.
- a / ı → mıyım
- e / i → miyim
- o / u → muyum
- ö / ü → müyüm
When speaking to multiple people or addressing someone formally, use the plural/formal suffix (-sınız, -siniz, -sunuz, -sünüz) on the question particle.
Third Person
Remember that the third person ("he", "she", "it", or specific nouns) does not take a personal suffix. Just use the standalone question particle that harmonizes with the word right before it.
