'nous' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe you can see an association between them that I can't see?

'avons choisi une maison en normandie first impressions?' is the wordplay.
I cannot quite see how this works, but
'en' is present in the answer.
'first' could be 'a' and 'a' is located in the answer.
The remaining letters 'cum' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for acumen that I've seen before include "The ability to make good and quick decisions" , "Wit" , "Sharpness of mind, good for business" , "perspicacity" , "Sharpness, penetration, quickness of perception" .)

I've seen this clue in The Telegraph.
