Final bid to secure an agreement? (8)
I believe the answer is:
contract
I believe this is a quadruple definition!!
'final bid' is the first definition.
'contract' can be an answer for 'bid' (contract is a kind of bid). I am unsure of the 'final' bit.
'to secure' is the second definition.
(thesaurus)
'an' is the third definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'agreement?' is the fourth definition.
(I know that agreement is a type of agreement)
Can you help me to learn more?
(Other definitions for contract that I've seen before include "Agree - reduce" , "Undertake" , "Become smaller" , "Arrangement to commit murder" , "Document setting out terms of agreement" .)
