Proposal of glib ideas (3)
I believe the answer is:
bid
'proposal' is the definition.
(a bid is a proposal or offer)
'of glib ideas' is the wordplay.
'of' says the answer is hidden in the clue.
'BID' is hidden in the letters of 'glib ideas'.
(Other definitions for bid that I've seen before include "Attempt, offer" , "Offer a price" , "Make offer for 20 Down" , "Order - offer" , "Offer a sum of money to buy" .)
