'a piece of jewellery' is the definition.
(I've seen this before)

'every right to fall' is the wordplay.
'every right' becomes 'ear' (I can't justify this - if you can you should believe this answer much more).
'to fall' becomes 'drop' (synonyms).
'ear'+'drop'='EARDROP'

'for' is the link.

Can you help me to learn more?

(Other definitions for eardrop that I've seen before include "It depends" , "A way to fill opening" , "little pendant" , "Piece of jewellery" , "piece for listeners" .)
