Hobbyist, one with a very full passport? (5,9)
I believe the answer is:
stamp collector
'full passport?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'hobbyist one with a very' is the wordplay.
'hobbyist' becomes 'collector'.
'one with' says to put letters next to each other.
'a very' becomes 'stamp' (I am not sure about this - if you are sure you should believe this answer much more).
'collector' put after 'stamp' is 'STAMP-COLLECTOR'.
Can you help me to learn more?
(Other definitions for stamp collector that I've seen before include "Philatelist" , "one makes albums" .)
