A playwright read out On The Beach (6)
I believe the answer is:
ashore
'on the beach' is the definition.
(I've seen this before)
'a playwright read out' is the wordplay.
'playwright' becomes 'shaw' (George Bernard Shaw).
'read out' indicates a 'sounds like' (homophone) clue.
'shaw' sounds like 'shore'.
'a'+'shore'='ASHORE'
(Other definitions for ashore that I've seen before include "Hoarse being no longer at sea" , "Hoarse (anag)" , "Returned to land" , "beach" , "Beached" .)
