That's difficult to answer. As written, I'd interpret "10:00" as the time when you made the arrangement. It's grammatically correct but ambiguous. Can you see a way to rearrange the words to fix this?Thank you, I will use your sentence but I am curious about the usage of 'arrange'. Can I use 'arrange a lesson' in the context below? (Interrogative sentences must end with a question mark.)
Hi, my name is x. I arranged a lesson with you at [STRIKE]10[/STRIKE] ten/10:00 ("10:00" is more natural).
Now I know it is ambiguous but is it correct?
No. If it's ambiguous, it's not correct.. . . Now I know it is ambiguous, but is it correct?
That's not natural or understandable in American English.I would say "fixed a lesson" rather than "arrange a lesson". "Arrange" means there is more to it than the time.
Or "our lesson is fixed at 10.00" (and you want to postpone it).
How about "fixed the date of the lesson"?
