Hear note initially shine (7)
I believe the answer is:
glisten
'shine' is the definition.
(synonyms)
'hear note initially' is the wordplay.
I cannot quite understand how this works, but
'hear' could be 'listen' (I've seen this before) and 'listen' is found in the answer.
'note' could be 'g' (musical note) and 'g' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for glisten that I've seen before include "Shine like something wet" , "Glow from reflection" , "Shine with reflected light" , "gloss" , "Singlet (anag.); tingles (anag.)" .)
