Have enough money for female to get in a car (6)
I believe the answer is:
afford
'have enough money for' is the definition.
(if you can afford it, you have enough money for it)
'female to get in a car' is the wordplay.
'female' becomes 'f' (abbreviation).
'to get in' means one lot of letters goes inside another.
'car' becomes 'ford' (ford is a make of car).
'a'+'ford'='aford'
'f' placed within 'aford' is 'AFFORD'.
(Other definitions for afford that I've seen before include "Provide; be able to pay for" , "Be able to buy" , "Have enough money to pay for" , "Give, provide" , "Run to" .)
