Inept or clumsy suggestion (7)
I believe the answer is:
pointer
'suggestion' is the definition.
(pointer can mean a suggestion or tip)
'inept or clumsy' is the wordplay.
'clumsy' is an anagram indicator.
'inept'+'or'='ineptor'
'ineptor' with letters rearranged gives 'POINTER'.
(Other definitions for pointer that I've seen before include "Suggestion" , "under control of mouse" , "Indicator" , "Dog; cursor" , "Sign" .)
