Apple hub first to advance from calm commerce (8)
I believe the answer is:
pressure
'apple hub first to advance from calm' is the definition.
I can't judge whether this definition defines the answer.
'commerce' is the wordplay.
I cannot really understand how this works, but
'commerce' could be 'press' (press is a kind of commerce) and 'press' is located in the answer.
The remaining letters 'ure' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pressure that I've seen before include "A force that compels" , "Type of organised group which tries to influence politicians" , "Coercion, intimidation" , "Force applied to a surface" , "Coercion or forceful persuasion" .)
