Playwright initially types out plays (6)
I believe the answer is:
sports
'plays' is the definition.
(I know this)
'playwright initially types out' is the wordplay.
'initially' indicates taking the first letters.
'types' becomes 'sorts' (I've seen this before).
'out' is an insertion indicator.
The first letter of 'playwright' is 'p'.
'p' placed into 'sorts' is 'SPORTS'.
(Other definitions for sports that I've seen before include "plays" , "Physical activities" , "Diversions" , "Wears; physical games" , "Wears, displays" .)
