Please remark about broken fist (7)
I believe the answer is:
satisfy
'please' is the definition.
(to satisfy someone is to please them)
'remark about broken fist' is the wordplay.
'remark' becomes 'say'' (to remark something is to say it).
'about' indicates putting letters inside.
'broken' indicates anagramming the letters.
'fist' is an anagram of 'tisf'.
'say' placed around 'tisf' is 'SATISFY'.
(Other definitions for satisfy that I've seen before include "indulge" , "Make contented or pleased" , "Provide enough" , "To convince" , "Meet the desires of" .)
