Offer to hold right flyer (4)
I believe the answer is:
bird
'flyer' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'offer to hold right' is the wordplay.
'offer' becomes 'bid' (bid is a kind of offer).
'to hold' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'bid' going around 'r' is 'BIRD'.
Can you help me to learn more?
(Other definitions for bird that I've seen before include "Dawn chorus etc - book by Sebastian Faulks" , "Feathered flyer" , "Fowl" , "Prison sentence - hawk, perhaps" , "Member of class Aves" .)
