Wait while an eccentric lady captures the heart of men (5)
I believe the answer is:
delay
'wait while' is the definition.
'delay' can be an answer for 'wait' (delaying is a kind of waiting). I am unsure of the 'while' bit.
'an eccentric lady captures the heart of men' is the wordplay.
'an eccentric' indicates an anagram.
'captures' is an insertion indicator.
'the heart of' indicates the central letters.
The middle of 'men' is 'e'.
'lady' is an anagram of 'dlay'.
'dlay' enclosing 'e' is 'DELAY'.
Can you help me to learn more?
(Other definitions for delay that I've seen before include "Time lapse" , "Hold back" , "Linger - slow down - put off" , "hold-up of train?" , "Postponement" .)
