Part of the body hurt when trapped in overturned craft (7)
I believe the answer is:
trachea
'part of the body' is the definition.
('trachea' is part of 'body')
'hurt when trapped in overturned craft' is the wordplay.
'hurt when' becomes 'ache' (synonyms. I am not sure about the 'when' bit.).
'trapped in' indicates putting letters inside.
'overturned' says the letters should be written in reverse.
'craft' becomes 'art' (both can mean cunning or trickery).
'art' in reverse letter order is 'tra'.
'ache' going inside 'tra' is 'TRACHEA'.
Can you help me to learn more?
(Other definitions for trachea that I've seen before include "get air supply through this" , "airway" , "body part" , "membranous tube" , "It connects the larynx and bronchi" .)
