We French have savvy (4)

Ross

I believe the answer is:

nous

I'm a little stuck... Click here to teach me more about this clue!

'savvy' is the definition.
(I've seen this before)

'we french' is the wordplay.
I cannot quite understand how this works, but
'we' could be 'us' and 'us' is found within the answer.
The remaining letters 'no' 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).

'have' acts as a link.

Can you help me to learn more?

(Other definitions for nous that I've seen before include "FT in Paris, say" , "Gumption" , "Knowledge, experience" , "we recognised in Nancy" , "We, in France, have common sense" .)
