Trespassers dropping pears with anxiety (6)
I believe the answer is:
stress
'anxiety' 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 stress that I've seen before include "Put weight on" , "Emotional tension" , "Highlight" , "Emphasis on anxiety?" , "nervous tension" .)
