See men’s ad possibly was comprehensible (4,5)
I believe the answer is:
made sense
'comprehensible' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes mean the same thing.
'see men's ad possibly' is the wordplay.
'possibly' indicates an anagram.
'see'+'mens'+'ad'='seemensad'
'seemensad' with letters rearranged gives 'MADE SENSE'.
'was' acts as a link.
Can you help me to learn more?
(Another definition for made sense that I've seen is " sounded OK".)
