University learners coming in to secure passage (6)
I believe the answer is:
gullet
'passage' is the definition.
(I know that gullet is a type of passage)
'university learners coming in to secure' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'learners' becomes 'LL' (L-plates are seen on learner drivers' cars).
'coming in to' is an insertion indicator.
'secure' becomes 'get' (secure can mean to get or obtain).
'u'+'ll'='ull'
'ull' placed into 'get' is 'GULLET'.
(Other definitions for gullet that I've seen before include "Food passage in the throat" , "part of canal" , "Food passage from mouth to stomach" , "Passage between pharynx and stomach" , "Oesophagus" .)
