Nothing between left and right — feasible view? (4,2)
I believe the answer is:
'feasible view?' is the definition.
'look on' can be an answer for 'view?' (to look on at something is to view it). I am unsure of the 'feasible' bit.
'nothing between left and right' is the wordplay.
'nothing between' becomes 'loo' (I can't justify this - if you can you should give a lot more credence to this answer).
'left' is a reversal indicator.
'and' becomes 'n' (common abbreviation for 'and').
'right' becomes 'ok' (both are affirmative answers).
'nok' back-to-front is 'kon'.
(Other definitions for look on that I've seen before include "Watch without becoming involved" , "Be a spectator, watch" , "Watch without getting involved" , "Be a spectator, observe" , "Watch as observer - dont get involved" .)
