Revealing experience, I said, key? (3-6)
I believe the answer is:
eye-opener
'revealing experience' is the definition.
The definition suggests a singular noun which matches the answer.
'i said key?' is the wordplay.
'said' indicates a 'sounds like' (homophone) clue.
'key?' becomes 'opener' (I've seen this before).
'i' sounds like 'eye'.
'eye'+'opener'='EYE-OPENER'
Can you help me to learn more?
(Other definitions for eye-opener that I've seen before include "A startling enlightenment!" , "Something startling" , "Startling revelation" , "Fact that surprises or enlightens in optical way" , "Fact that brings great surprise - wakes you up" .)
