Preguntas frecuentes (8)
Yes, they mean the same thing. `can't` is a contraction and is very common in speaking. `cannot` is more formal and is always written as one word.
Not directly. We usually use `be able to` for the future (e.g., 'I will be able to come'). However, for scheduled events, we sometimes use `can` (e.g., 'I can meet you tomorrow').
Because `can` is a modal verb. Modal verbs are special and never change their form, no matter who the subject is.
They are very similar. `can` is more general and covers physical ability, while `know how to` specifically refers to learned skills. 'I can breathe' (physical) vs 'I know how to drive' (skill).
It is almost always written as one word: `cannot`. You only see `can not` if the 'not' belongs to a different part of the sentence, which is very rare.
Yes! In modern English, 'Can I...?' is perfectly acceptable for permission, though 'May I...?' is more formal.
Focus on the vowel. In `can`, the vowel is short and weak. In `can't`, the vowel is stronger and longer. In American English, the 't' is often a 'stop' in the throat.
No. You cannot put two modal verbs together. Instead of 'will can', you must say `will be able to`.
