Become older than the thoroughfare (7)
I believe the answer is:
passage
'thoroughfare' is the definition.
(thesaurus)
'become older than' is the wordplay.
I cannot quite see how this works, but
'become older' could be 'age' (I've seen this in another clue) and 'age' is located in the answer.
The remaining letters 'pass' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for passage that I've seen before include "crossing" , "course" , "Literary extract" , "Way through; part of text" , "Section of text; journey" .)
