'make charming' is the definition.
I can't judge whether this definition defines the answer.

'final piece on organ' is the wordplay.
'final piece' becomes 'end' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'organ' becomes 'ear' (the ear is an organ).
'end'+'ear'='ENDEAR'

Can you help me to learn more?

(Other definitions for endear that I've seen before include "Make loveable" , "Evoke love - charm" , "Make popular" , "Cause to like" , "Neared (anag.)" .)

I've seen this clue in The Times.
