Outdoor garment for actor in a play (8)
I believe the answer is:
raincoat
'outdoor garment' is the definition.
'raincoat' can be an answer for 'garment' (raincoat is a kind of garment). I'm not certain of the 'outdoor' bit.
'actor in a play' is the wordplay.
'play' indicates anagramming the letters.
'actor'+'in'+'a'='actorina'
'actorina' with letters rearranged gives 'RAINCOAT'.
'for' is the link.
Can you help me to learn more?
(Other definitions for raincoat that I've seen before include "which should keep water out" , "protection against the elements" , "Water-resistant outer garment" , "Macintosh - with 22a" , "Protective garment for Croatian" .)
