Spend time in the corridor (7)
I believe the answer is:
passage
'the corridor' is the definition.
(thesaurus)
'spend time' is the wordplay.
'spend' becomes 'pass' ('pass' can be a synonym of 'spend').
'time' becomes 'age' (age is a kind of time).
'pass'+'age'='PASSAGE'
'in' acts as a link.
(Other definitions for passage that I've seen before include "Channel" , "Excerpt" , "Some reading" , "Book extract; transit" , "Way through; part of text" .)
