Discover female in Dartford originally (4)
I believe the answer is:
find
'discover' is the definition.
(I know that discover can be written as find)
'female in dartford originally' is the wordplay.
'female' becomes 'f' (abbreviation).
'originally' says to take the initial letters.
The initial letter of 'dartford' is 'd'.
'f'+'in'+'d'='FIND'
(Other definitions for find that I've seen before include "Locate or discover" , "Come across" , "Discover by chance" , "Encounter, locate" , "Acquisition" .)
