can i fix you a cup of tea
Can i fix you a cup of tea.
Yes this is a question.
To save this thread running for weeks, here is how your sentence should look:
Can I fix you a cup of tea?
I have underlined the relevant points.
1) Capital letter at the beginning.
2) Always capitalise "I".
3) It's a question, so it must have a question mark at the end.
Your original question was "Is this sentence OK?" (note the capitalisation and punctuation again).
In AmE, I would say yes. In BrE, we say "Can/shall I make you a cup of tea?"
Not a teacher.
"May I..." is the formal, proper way to ask, but many or most natives will say "Can I..."
