Cryptic answers lacking any gist (6)
I believe the answer is:
wrasse
'gist' is the definition.
Although both the answer and definition are singular nouns, I can'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 wrasse that I've seen before include "catch in the deep" , "Type of fish" , "Swears about the tropical marine fish with strong teeth" , "Fish - swears (anag)" , "Bony fish" .)
