Intentionally exasperating? (6)
I believe the answer is:
trying
'exasperating?' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for trying that I've seen before include "Tiresome" , "Annoying; sampling" , "Sitting in judgement" , "Stressful" , "Vexatious - having a go" .)
