Charge for trip (5)
I believe the answer is:
sally
I believe this is a double definition.
'charge' is the first definition.
(thesaurus)
'trip' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for sally that I've seen before include "Girl" , "A sortie or witty remark" , "one in 3 the 12 30 [DROP the DEAD DONKEY]" , "Witty riposte" , "Sortie - Gracie Fields song" .)
