Not lewd, wild or disappointed (3,4)
I believe the answer is:
let down
'disappointed' is the definition.
(I've seen this before)
'not lewd wild' is the wordplay.
'wild' indicates an anagram.
'not'+'lewd'='notlewd'
'notlewd' is an anagram of 'LET-DOWN'.
'or' is the link.
(Other definitions for let down that I've seen before include "Disappoint, fail to keep promise" , "blow" , "disillusionment" , "Failed - to deflate a tyre - disappointed" , "Disappoint, fail to support" .)
