Succeed in giving directions to the girl (5)
I believe the answer is:
ensue
'succeed' is the definition.
(I've seen this before)
'giving directions to the girl' is the wordplay.
'giving' is a charade indicator (letters next to each other).
'directions' becomes 'en' (I've seen this in other clues).
'to the girl' becomes 'sue' (girl's name).
'en' put next to 'sue' is 'ENSUE'.
'in' acts as a link.
(Other definitions for ensue that I've seen before include "Occur as a result (of)" , "Befall" , "Proceed" , "Leading directly to" , "Happen afterwards as a result" .)
