Under canvas, reportedly getting saturated? (7)
I believe the answer is:
intense
'saturated?' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for intense that I've seen before include "say, description of campers?" , "Strong in degree or emotion" , "amplified?" , "Acute, exteme" , "Vivid, concentrated" .)
