Rodney might be over there (6)
I believe the answer is:
yonder
'over there' is the definition.
(archaic preposition meaning 'over there')
'rodney might be' is the wordplay.
'might be' is an anagram indicator.
'rodney' is an anagram of 'YONDER'.
(Other definitions for yonder that I've seen before include "See Rodney over there" , "Over there, a long time ago" , "Over there (poetic)" , "to place indicated" , "that one" .)
