Busy architect gets rid of art (6)
I believe the answer is:
hectic
'busy' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for hectic that I've seen before include "Marked by intense activity" , "'Rushed, madly busy (6)'" , "Full of frantic activity" , "Extremely busy - fevered" , "'Excited, flustered or rushed (6)'" .)
