Touch lucky, at first, after charge (4)
I believe the answer is:
feel
'touch' is the definition.
(feeling is a kind of touching)
'lucky at first after charge' is the wordplay.
'at first' suggests taking the first letters.
'after' says to put letters next to each other.
'charge' becomes 'fee' (fee is a kind of charge**).
The first letter of 'lucky' is 'l'.
'l' put after 'fee' is 'FEEL'.
(Other definitions for feel that I've seen before include "Experience (an emotion)" , "Instinct" , "Experience, perceive" , "Perceive, sense" , "Consider" .)
