Impelled to depress assembly (7)
I believe the answer is:
pressed
'impelled' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'depress assembly' is the wordplay.
'assembly' indicates anagramming the letters.
'depress' with letters rearranged gives 'PRESSED'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for pressed that I've seen before include "Coerced" , "in a big hurry" , "under some strain" , "Argued strongly and exerted force" , "Ironed" .)
