Variety of trout swallowing a piece of bait? (6)
I believe the answer is:
turbot
'bait?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'variety of trout swallowing a piece' is the wordplay.
'variety of' indicates anagramming the letters.
'swallowing' means one lot of letters goes inside another.
'a piece' becomes 'b' (abbreviation for bishop).
'trout' is an anagram of 'turot'.
'turot' enclosing 'b' is 'TURBOT'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for turbot that I've seen before include "Type of fish" , "Swimmer" , "[SOMETHING FISHY]" , "Large brownish European flatfish" , "Flatfish - trout B (anag)" .)
