See all right with this facial expression (4)
I believe the answer is:
look
'this facial expression' is the definition.
(I've seen this before)
'see all right' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'all right' becomes 'ok' (synonyms).
'lo'+'ok'='LOOK'
'with' is the link.
(Other definitions for look that I've seen before include "Peer" , "Mien" , "Behold" , "Search (with the eyes)" , "Watch, observe" .)
