A priest's building for tramps? (8)
I believe the answer is:
traipses
'tramps?' is the definition.
(I've seen this before)
'a priest's building' is the wordplay.
'building' indicates anagramming the letters.
'a'+'priests'='apriests'
'apriests' is an anagram of 'TRAIPSES'.
'for' is the link.
(Other definitions for traipses that I've seen before include "Walks pointlessly or tediously" , "Walk tediously, plods" , "Tramps" .)
