Unfortunately I'd liked men to be of the same opinion (4-6)
I believe the answer is:
like-minded
'to be of the same opinion' is the definition.
I can't tell whether this defines the answer.
'unfortunately i'd liked men' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'id'+'liked'+'men'='idlikedmen'
'idlikedmen' is an anagram of 'LIKE-MINDED'.
Can you help me to learn more?
(Other definitions for like-minded that I've seen before include "naturally sympathetic?" , "having similar outlook" .)
