Could make one dry over there (6)
I believe the answer is:
yonder
'over there' is the definition.
(archaic preposition meaning 'over there')
'could make one dry' is the wordplay.
'could make' is an anagram indicator.
'one'+'dry'='onedry'
'onedry' is an anagram of 'YONDER'.
(Other definitions for yonder that I've seen before include "to place indicated" , "Over there, a long time ago" , "Over there (poetic)" , "Over there, of old." , "At a distance but in sight" .)
