Propositioned general, a little uneasy (2,4)
I believe the answer is:
on edge
'uneasy' is the definition.
(thesaurus)
'propositioned general a little' is the wordplay.
'a little' says the answer is hidden in the clue.
'ON EDGE' is hidden in the letters of 'propositioned general'.
(Other definitions for on edge that I've seen before include "Fidgety, nervous" , "Apprehensive" , "Tense and irritable, with nerves stretched" , "close to border" , "Tense and irritable, very nervous" .)
