Tiring journey of a priest abroad (7)

I believe the answer is:
traipse
'tiring journey' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps you can see an association between them that I can't see?
'a priest abroad' is the wordplay.
'abroad' is an anagram indicator (abroad can mean moving around).
'a'+'priest'='apriest'
'apriest' anagrammed gives 'TRAIPSE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for traipse that I've seen before include "Trudge around" , "Pirates (anag) -- walk without 9" , "travel wearily" , "Plod - trek" , "make slow progress" .)
