Nasal cavity opening discussed in journo's trilogy (7)
I believe the answer is:
nostril
'nasal cavity' is the definition.
(I've seen this before)
'in journo's trilogy' is the wordplay.
'in' says the answer is hidden in the clue.
'NOSTRIL' is hidden in the letters of 'journos trilogy'.
'opening discussed' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for nostril that I've seen before include "Nose hole" , "Nasal opening" , "Nasal feature" , "Nasal aperture" , "Bit of a breather" .)
