Of paramount importance, it appears, in general (7)
I believe the answer is:
overall
'in general' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for overall that I've seen before include "It protects a worker" , "Omnipotent" , "Comprehensive - protective garment" , "altogether" , "Protective cover for worker" .)
