Figure fit to be possibly justified (7)
I believe the answer is:
tenable
'possibly justified' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes mean the same thing.
'figure fit' is the wordplay.
'figure' becomes 'ten' (ten is a number).
'fit' becomes 'able' (similar in meaning).
'ten'+'able'='TENABLE'
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for tenable that I've seen before include "Believable" , "Late Ben (anag.)" , "Well-founded" , "Based on sound reasoning or evidence" , "Able to be defended against attack or objection" .)
