Nameless job I had to offer (3)
I believe the answer is:
bid
'offer' is the definition.
(synonyms)
'nameless job i had' is the wordplay.
'nameless job' becomes 'b' (I can't explain this - if you can you should believe this answer much more).
'i had' becomes 'i'd' (contraction).
'b'+'id'='BID'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for bid that I've seen before include "Propose a payment" , "Offer a sum of money to buy" , "Sum offered at an auction" , "Tender (for work)" , "Offer (for); demand" .)
