Sally may see almost nothing in French about job (7)
I believe the answer is:
riposte
'sally' is the definition.
(both can mean a witty remark)
'almost nothing in french about job' is the wordplay.
'almost' means to remove the last letter (almost the whole word is kept).
'nothing in french' becomes 'rien' ('nothing' in French).
'about' indicates putting letters inside.
'job' becomes 'post' (post is a kind of job).
'rien' with its last letter taken off is 'rie'.
'rie' going around 'post' is 'RIPOSTE'.
'may see' acts as a link.
(Other definitions for riposte that I've seen before include "Counter-thrust" , "Rejoinder" , "Quick retort or return hit in fencing" , "Witty comeback" , "Reply, response" .)
