Happening to find Greek character on turf in Central Greece? (7)
I believe the answer is:
episode
'happening' is the definition.
(episode is a kind of happening)
'greek character on turf in central greece?' is the wordplay.
'greek character' becomes 'pi' (letter from the Greek alphabet**).
'on' means one lot of letters go next to another.
'turf' becomes 'sod' ('sod' can be a synonym of 'turf').
'in' means one lot of letters goes inside another.
'central' indicates the central letters.
The centre of 'greece' is 'ee'.
'pi'+'sod'='pisod'
'pisod' put within 'ee' is 'EPISODE'.
'to find' is the link.
(Other definitions for episode that I've seen before include "Part of TV series" , "A chapter or incident" , "Story instalment" , "Event or series of events in a story" , "Distinctive incident" .)
