Short race organised for a play group (9)
I believe the answer is:
orchestra
'a play group' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe there's an association between them I don't understand?
'short race organised' is the wordplay.
'organised' indicates an anagram.
'short'+'race'='shortrace'
'shortrace' with letters rearranged gives 'ORCHESTRA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for orchestra that I've seen before include "Gamelan, for instance" , "Large musical group" , "Instrumental group" , "bandsmen?" , "Other cars (anag.)" .)
