Curse this writer audibly after upsetting experience (4,3)
I believe the answer is:
evil eye
'curse' is the definition.
(I've seen this before)
'writer audibly after upsetting experience' is the wordplay.
'writer' becomes 'I' (the person who is writing these clues).
'audibly' indicates a 'sounds like' (homophone) clue.
'after' says to put letters next to each other.
'upsetting' says the letters should be written in reverse.
'experience' becomes 'live' (living is a kind of experiencing).
'i' is a homophone of 'eye'.
'live' in reverse letter order is 'evil'.
'eye' after 'evil' is 'EVIL-EYE'.
'this' is the link.
(Other definitions for evil eye that I've seen before include "Gaze or stare believed to cause harm" , "Malign influence" , "Depraved optic with superstitious curse" , "Supposedly harmful glance" , "Look with the power to inflict harm" .)
