Chap is to walk with female (7)
I believe the answer is:
stephen
'chap' is the definition.
(stephen is a male name)
'walk with female' is the wordplay.
'walk' becomes 'step' (I've seen this before).
'with' means one lot of letters go next to another.
'female' becomes 'hen' (hen is a kind of female).
'step'+'hen'='STEPHEN'
'is to' is the link.
(Other definitions for stephen that I've seen before include "-- Hawking (A Brief History of Time)" , "-- Hawking, English physicist" , "Boy" , "First Christian martyr" , "Male" .)
