My sentence says
Coventry city centre's main transport links.
but there is a red line under "centre's" in MS word. Is it "centres" or "centre's"? I thought that you use an apostrophe for belonging.
Thanks in advance.
Do you have MS Word configured to be checking for American English or British English? The British spell the word as "centre" and Americans spell it as "center". If MS Word is checking American English, it will mark "centre" as incorrect.
The correct possessive form of "centre" is "centre's" and the correct possessive form of "center" is " center's".
