It's fine to support worker on note (7)
I believe the answer is:
elegant
'it's fine' is the definition.
(similar in meaning)
'support worker on note' is the wordplay.
'support' becomes 'leg' (leg is a kind of support).
'worker' becomes 'ant' (worker is a type of ant).
'on' is a charade indicator (letters next to each other).
'note' becomes 'e' (musical note).
'leg'+'ant'='legant'
'legant' after 'e' is 'ELEGANT'.
'to' is the link.
(Other definitions for elegant that I've seen before include "Modish" , "Tasteful and refined in appearance" , "Debonair, stylishly dressed" , "Well-turned" , "luxurious style?" .)
