Men held by strange gift of imagination perhaps (7)
I believe the answer is:
figment
'imagination perhaps' is the definition.
I can't judge whether this defines the answer.
'men held by strange gift' is the wordplay.
'held by' is an insertion indicator.
'strange' is an anagram indicator.
'gift' is an anagram of 'figt'.
'men' placed into 'figt' is 'FIGMENT'.
'of' is the link.
Can you help me to learn more?
(Other definitions for figment that I've seen before include "Contrived idea" , "Thought" , "Imagined object" , "Imaginary thing" , "fantastic idea" .)
