Holding a green ticket for the trips (8)
I believe the answer is:
passages
'the trips' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'holding a green ticket' is the wordplay.
'holding' means one lot of letters goes inside another.
'a green' becomes 'sage' (shade of green).
'ticket' becomes 'pass' (pass is a kind of ticket).
'sage' placed inside 'pass' is 'PASSAGES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for passages that I've seen before include "Sections of a text" , "Texts" , "journeys" , "Paths between buildings" , "sections of the speech" .)
