Farther away than that one over there in bed (6)
I believe the answer is:
beyond
'farther away than that' is the definition.
'beyond' can be an answer for 'farther' (I've seen this before). I am not certain of the rest of the definition.
'one over there in bed' is the wordplay.
'one over there' becomes 'yon' (archaic word meaning 'over there').
'in' indicates putting letters inside.
'yon' put within 'bed' is 'BEYOND'.
Can you help me to learn more?
(Other definitions for beyond that I've seen before include "Past" , "unknown" , "Farther along in space, time or degree" , "(The) hereafter" , "Better than" .)
