Be focused and cordial (11)
I believe the answer is:
concentrate
'cordial' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'be focused' is the wordplay.
I cannot really understand how this works, but
'be' could be 'rate' (rating is a kind of being) and 'rate' is found in the answer.
The remaining letters 'concent' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for concentrate that I've seen before include "Think" , "What thinker may have to do" , "Increase the strength of (a solution)" , "Focus one's thoughts" , "get solution in chemistry" .)
