Persuade someone to buy ale with no head - presumably one has lots to sell? (10)
I believe the answer is:
auctioneer
'persuade someone to buy ale with no head presumably one' is the definition.
I can't judge whether this definition defines the answer.
'lots to sell?' is the wordplay.
'lots' becomes 'eer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'sell?' becomes 'auction' (auctioning is a kind of selling).
'eer' put after 'auction' is 'AUCTIONEER'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for auctioneer that I've seen before include "one that has lots to offer" , "One inviting bids for lots" , "One selling lots" .)
