"Where is the fly?"

Translation: Où est la mouche ?

[rose700778]

is there really an accent on the 'u' on ou?

[relox84]

Yes. It doesn't change the pronounciation, its purpose is to disambiguate from the word 'ou' which means 'or'. Same thing for 'a' (has) and 'à' (to/at).

[MakenzieCo347542]

Is moustique an acceptable synonym for mouche?

[Sitesurf]

No, "un moustique" is a mosquito.
