Saint gets everything to come to a standstill (5)
I believe the answer is:
stall
'come to a standstill' is the definition.
(I've seen this in another clue)
'saint gets everything' is the wordplay.
'saint' becomes 'st' (abbreviation).
'gets' means one lot of letters go next to another.
'everything' becomes 'all' (all things).
'st'+'all'='STALL'
'to' acts as a link.
(Other definitions for stall that I've seen before include "Be evasive" , "Come to a halt" , "Part of the stable" , "Theatre seat" , "Play for time" .)
