Not wanted to otherwise hug snout (8)
I believe the answer is:
unsought
'not wanted' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs sometimes define each other.
'otherwise hug snout' is the wordplay.
'otherwise' indicates an anagram.
'hug'+'snout'='hugsnout'
'hugsnout' with letters rearranged gives 'UNSOUGHT'.
'to' is the link.
Can you help me to learn more?
(Other definitions for unsought that I've seen before include "unlike Sir Percy Blakeney" , "Untried" , "Not looked for or desired" , "not requested" .)
