Questions & Answers about Můžete si vybrat jakýkoli den.
Můžete means you can or you may.
It is the 2nd person plural form of moci = to be able / can. In Czech, this form is used for:
- you all can
- you can when speaking politely to one person
So this sentence can address either several people or one person formally.
Because moci is an irregular verb.
Its present-tense forms are built from the stem můž-, not from moc-:
- můžu / mohu = I can
- můžeš = you can
- může = he/she/it can
- můžeme = we can
- můžete = you can
- můžou / mohou = they can
So moci → můžete is something you mostly just have to learn as part of the verb’s conjugation.
Because after a modal verb like moci (can), Czech normally uses the infinitive of the main verb.
So:
- Můžete = you can
- vybrat = choose
Together: Můžete vybrat = You can choose
This works just like English can choose.
