Mohu si půjčit váš telefon?
When to use
This is a polite way to ask if you can temporarily use someone else's phone, usually when you have an urgent need and your own phone is unavailable or unusable.
How it works
The phrase means 'May I borrow your phone?'. 'Mohu si' - May I (for myself) 'půjčit' - borrow 'váš telefon' - your phone (formal/plural).
Grammar
Similar to phrase 4, 'mohu' is 'I can/may'. 'Si půjčit' means 'to borrow for oneself'. 'Váš' is the possessive pronoun for the formal 'vy' (you), agreeing with the masculine noun 'telefon'.
Notes
Ask to borrow someone's phone in an urgent situation.
