Rate poet engineered for stage production (8)
I believe the answer is:
operetta
'stage production' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'rate poet engineered' is the wordplay.
'engineered' indicates an anagram.
'rate'+'poet'='ratepoet'
'ratepoet' anagrammed gives 'OPERETTA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for operetta that I've seen before include "Singing" , "Showboat or The Gondoliers, say" , "Show" , "The Merry Widow, for example" , "some music theatre" .)
