"She has doubts about her husband."

Translation: Elle doute de son mari.

[BampaOwl]

How would you distinguish in French "She has doubts about her husband", as here, and "She doubts her husband" (i.e. she does not believe her husband)?

[sharmainelanae]

I would say "sur" is what makes the difference here.
Elle a des doutes sur son mari.

Elle doute son mari.

I'm assuming that the noun "doubt" is the same as the verb "to doubt".

[BrainyPirate]

why does the sentence take "sur" with "avoir doute", but "de" with just "douter"?

[pasunparisien]

I tried "Elle a des doutes à propos de son mari." and it was accepted. Quelle surprise !

[L0ve_Joy]

Hmmm... gotta trust a woman's intuition!

[romaeterna]

Isn't "elle s'en doute de son mari" also possible?

[doublelingot]

No. Elle doute de son mari. Elle en doute.

[esowl]

What do we think of “Elle a des doutes concernant son mari,” which was rejected?

[jimnicolson]

Not a native French speaker but this was my first thought but given Duo's (random) literal approach, I did a check here http://www.wordreference.com/enfr/doubts%20about

Switched to "Elle a des doutes sur son mari." which was accepted

The french and english sentences are not saying the same thing.
