Letting us hear some effusive language (4)
I believe the answer is:
gush
'effusive language' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'letting us hear some' is the wordplay.
'some' says the answer is hidden in the clue.
'GUSH' is hidden within 'letting us hear'.
Can you help me to learn more?
(Other definitions for gush that I've seen before include "Spout powerfully" , "Spurt" , "Flood out - enthuse" , "Speak effusively" , "Flow unceasingly" .)
