Cat that’s trapped a rook’s airway (6)
I believe the answer is:
larynx
'airway' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'cat that's trapped a rook's' is the wordplay.
'cat' becomes 'lynx' (lynx is a kind of cat).
'that's trapped' indicates putting letters inside.
'rook' becomes 'r' (abbreviation in chess).
'a'+'r'='ar'
'lynx' going around 'ar' is 'LARYNX'.
Can you help me to learn more?
(Other definitions for larynx that I've seen before include "Air passage" , "Site of the vocal cords" , "Where growls come from" , "Source of squeaks" , "part of throat with vocal chords" .)
