Flannel cook squeezes well! (8)
I believe the answer is:
flummery
'well' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'flannel cook squeezes' is the wordplay.
'flannel' becomes 'lumme' (I can't justify this - if you can you should give a lot more credence to this answer).
'cook' becomes 'fry' (fry cook is a kind of cook).
'squeezes' indicates putting letters inside (squeeze can mean hug or embrace).
'lumme' placed into 'fry' is 'FLUMMERY'.
Can you help me to learn more?
(Other definitions for flummery that I've seen before include "Meaningless pomp" , "Meaningless ceremonies and flattery" , "Load of rot" , "Dish of eggs and sugar" .)
