Husband isnt mad about reminders (5)
I believe the answer is:
hints
'reminders' is the definition.
(I've seen this in another clue)
'husband isnt mad about' is the wordplay.
'husband' becomes 'h' ().
'mad' indicates anagramming the letters.
'about' is an insertion indicator.
'isnt' anagrammed gives 'ints'.
'h' put into 'ints' is 'HINTS'.
(Other definitions for hints that I've seen before include "Suggestions" , "Slight indications" , "Tips" .)
