Glance from king on throne (4)
I believe the answer is:
look
'glance' is the definition.
(I know that glance is a kind of look)
'king on throne' is the wordplay.
'king' becomes 'k' (chess abbreviation).
'on' means one lot of letters go next to another.
'throne' becomes 'loo' (both can mean a toilet).
'k' put after 'loo' is 'LOOK'.
'from' is the link.
(Other definitions for look that I've seen before include "Inspect" , "Get an eyeful" , "Seem" , "Search (with the eyes)" , "Direct the eye to" .)
