Frolic on adult beach in Spain (5)
I believe the answer is:
playa
'beach in spain' is the definition.
'playa' can be an answer for 'beach' (I have seen 'Spanish beach ' mean 'playa' so perhaps 'beach' could also mean 'playa'). I'm not sure about the 'in spain' bit.
'frolic on adult' is the wordplay.
'frolic' becomes 'play' (synonyms).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'adult' becomes 'a' (abbreviation).
'play'+'a'='PLAYA'
Can you help me to learn more?
(Other definitions for playa that I've seen before include "piece of land liable to flood" , "Spanish beach" , "bed in Spain" , "Expanse of dry land" , "lake after rainfall" .)
