Questions & Answers about Czy możesz podać mi jeszcze jeden talerz?
Czy is a yes/no question marker. It does not really translate to a single English word, but it functions a bit like the English use of Do/Can/Is... ? at the start of a question.
So:
- Możesz podać mi jeszcze jeden talerz. = You can pass me one more plate.
- Czy możesz podać mi jeszcze jeden talerz? = Can you pass me one more plate?
In everyday Polish, people often omit czy and just use rising intonation:
- Możesz podać mi jeszcze jeden talerz?
That is also completely natural.
Możesz is the 2nd person singular form of móc, which means can / to be able to.
Conjugation of móc in the present tense:
- mogę = I can
- możesz = you can
- może = he/she/it can
- możemy = we can
- możecie = you all / you plural can
- mogą = they can
So możesz is used because the sentence is addressed to one person in an informal way.
