Very busy architect worked without art (6)
I believe the answer is:
hectic
'very busy' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hectic that I've seen before include "Frenetic" , "Frantically active" , "Frenzied" , "'Excited, flustered or rushed (6)'" , "Agitated and rushed" .)
