Person on golf course endlessly — is husband ungentlemanly? (7)
I believe the answer is:
caddish
'ungentlemanly?' is the definition.
(I've seen this before)
'person on golf course endlessly is husband' is the wordplay.
'person on golf course' becomes 'caddy' (person carrying a golfer's clubs).
'endlessly' means to remove the last letter.
'husband' becomes 'h'.
'caddy' with its final letter removed is 'cadd'.
'cadd'+'is'+'h'='CADDISH'
(Other definitions for caddish that I've seen before include "Misbehaving" , "like a scoundrel" , "Ungentlemanly sort of behaviour" , "pretty low" , "behaving dishonourably" .)
