Caveat ..., let the buyer beware (6)
I believe the answer is:
emptor
'caveat' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for emptor that I've seen before include "See 15" , "... emptor, let the buyer beware" , "'Caveat..., let the buyer beware (6)'" , "A Latin buyer - let him caveat" .)
