School left recreational activity (5)
I believe the answer is:
sport
'recreational activity' is the definition.
'sport' can be an answer for 'activity' (sport is a kind of activity). I am unsure of the 'recreational' bit.
'school left' is the wordplay.
'school' becomes 'S'.
'left' becomes 'port' (left side of a ship - opposite of starboard).
's'+'port'='SPORT'
Can you help me to learn more?
(Other definitions for sport that I've seen before include "Physical recreation" , "form of exercise?" , "Game; display" , "Fun; wear" , "Recreation, play" .)
