Adult expressed hint of exasperation (5)
I believe the answer is:
groan
'hint of exasperation' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'adult expressed' is the wordplay.
'adult' becomes 'grown' (synonyms).
'expressed' shows a homophone (sound like).
'grown' is a homophone of 'GROAN'.
Can you help me to learn more?
(Other definitions for groan that I've seen before include "Expression of pain or disapproval" , "Titus -- (Mervyn Peake)" , "Utterance expressing pain or disapproval" , "Organ (anag) - lament" , "express disapproval" .)
