Aunt Juliette's first trip (5)
I believe the answer is:
jaunt
'trip' is the definition.
(I know that trip can be written as jaunt)
'aunt juliette's first' is the wordplay.
'juliette' becomes 'j' (this might be a standard abbreviation which I don't know about).
'first' is a charade indicator (letters next to each other).
'aunt' put after 'j' is 'JAUNT'.
Can you help me to learn more?
(Other definitions for jaunt that I've seen before include "Ramble - excursion" , "Pleasurable trip" , "Pleasure journey" , "Short excursion for pleasure" , "Pleasure trip" .)
