Tender bishop gets one note (3)
I believe the answer is:
bid
'tender' is the definition.
(synonyms)
'bishop gets one note' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'gets' says to put letters next to each other.
'one' becomes 'I' (Roman numeral).
'note' becomes 'd' (musical note).
'b'+'i'+'d'='BID'
(Other definitions for bid that I've seen before include "Sum offered at an auction" , "Offer a price" , "Order - offer" , "Offer a sum of money to buy" , "Propose a payment" .)
