Likable general speaking after pressure to confess (8)
I believe the answer is:
pleasing
'likable' is the definition.
(thesaurus)
'general speaking after pressure to confess' is the wordplay.
'general' becomes 'lee' (Robert E. Lee - US revolutionary commander).
'speaking' indicates a 'sounds like' (homophone) clue.
'after' is a charade indicator (letters next to each other).
'pressure' becomes 'p' (abbreviation).
'to confess' becomes 'sing' (I've seen this before).
'lee' is a homophone of 'lea'.
'lea' after 'p' is 'plea'.
'plea'+'sing'='PLEASING'
(Other definitions for pleasing that I've seen before include "Pleasurable; satisfying" , "making one happy" , "Satisfying or appealing" , "Delightful" , "agreeable - with 13d" .)
