Fancied one at the party we hear (7)
I believe the answer is:
guessed
'fancied' is the definition.
Although both the answer and definition are past participle verbs, I cannot see how one could define the other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for guessed that I've seen before include "Hazarded, estimated" , "perhaps got in one" , "Estimated correctly" , "took a shot" , "Conjectured" .)
