Roll with changing tides when launched (8)
I believe the answer is:
baptised
'launched' is the definition.
Although both the answer and definition are past participle verbs, I can't see how they can define each other.
'roll with changing tides' is the wordplay.
'roll' becomes 'bap' (bap can mean a bread roll).
'with' is a charade indicator (letters next to each other).
'changing' is an anagram indicator.
'tides' with letters rearranged gives 'tised'.
'bap'+'tised'='BAPTISED'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for baptised that I've seen before include "Given a name" , "Christened" , "wet by a sprinkler?" , "Conducted religious rite of sprinkling water on" , "Named" .)
