One-piece not being considered (5)
I believe the answer is:
apart
'being considered' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'one-piece' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'piece' becomes 'part' (synonyms).
'a'+'part'='APART'
'not' is the link.
Can you help me to learn more?
(Other definitions for apart that I've seen before include "in bits" , "set aside" , "away" , "Separately, aside" , "(Break) into pieces" .)
