In dentist, as terrified, have trying experience? (5)
I believe the answer is:
taste
'trying experience?' is the definition.
(I've seen this in another clue)
'in dentist as terrified' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TASTE' is hidden within 'dentist as terrified'.
'have' acts as a link.
(Other definitions for taste that I've seen before include "One of the senses" , "Artistic appreciation" , "Try (food)" , "to eat in small amounts" , "Judgment" .)
