Preguntas frecuentes (8)
Yes. While some traditionalists prefer `may`, `can` is standard and correct in modern English for permission.
`Can` is for permission/ability; `can't` is the negative form (cannot).
It's better to use `could` or `may` in a formal email to sound more professional.
Because `can` is a modal verb, and modal verbs never change their ending.
No, it's a request. It's a polite way to ask someone to do something.
In American English, it's like `kant` (rhymes with pant). In British English, it's often `kahnt`.
No. Never use `to` after `can`. Just say `Can I go?`.
Use `could` when you want to be extra polite or when asking a stranger for a favor.
