Hesitate, seeing female change (6)
I believe the answer is:
falter
'hesitate' is the definition.
(faltering is a kind of hesitating)
'female change' is the wordplay.
'female' becomes 'f' (abbreviation).
'change' becomes 'alter' ('alter' can be a synonym of 'change'**).
'f'+'alter'='FALTER'
'seeing' is the link.
(Other definitions for falter that I've seen before include "Hesitate, be uncertain" , "Lose momentum" , "Hesitate, waver" , "flag" , "Hesitate, vacillate" .)
