"Ils ont accepté notre invitation avec enthousiasme."

Translation: They accepted our invitation enthusiastically.

[InvertedGo]

Here's hoping they also accept "...with enthusiasm".

[tachyonashley123]

They do.

[MandyB11]

Also accepted is "they enthusiastically accepted our invitation."

Is accepté singular because it refers to the invitation? Or does it (as I initially thought) refer to "they", and if so, why isn't it in the plural like the other avoir passé composé verbs? Thanks!

'They accepted enthusiastically our invitation' was rejected. I fail to see the point.
