Badly hit the first woman to steal (6)
I believe the answer is:
thieve
'to steal' is the definition.
(I know this)
'badly hit the first woman' is the wordplay.
'badly' is an anagram indicator.
'the first woman' becomes 'Eve' (first woman in the bible).
'hit' with letters rearranged gives 'thi'.
'thi'+'eve'='THIEVE'
(Other definitions for thieve that I've seen before include "Take illegally" , "Steal things" , "Rob" , "Nick things" , "Pilfer" .)
