Boat unaffected after capsizing? (5)
I believe the answer is:
event
'capsizing?' is the definition.
(capsizing is a kind of event)
'boat unaffected after' is the wordplay.
'boat' becomes 'e'.
'unaffected' becomes 'vent' (I can't justify this - if you can you should believe this answer much more).
'after' says to put letters next to each other.
'e'+'vent'='EVENT'
Can you help me to learn more?
(Other definitions for event that I've seen before include "contest in programme" , "Anything which happens" , "tournament" , "celebration?" , "'Occurrence, occasion (5)'" .)
