Abandoned, see me entertaining singles (8)
I believe the answer is:
lonesome
'abandoned' is the definition.
(I've seen this before)
'see me entertaining singles' is the wordplay.
'see' becomes 'lo' (archaic word meaning 'look!').
'entertaining' indicates putting letters inside.
'singles' becomes 'ones' ('one' can be a synonym of 'single').
'lo'+'me'='lome'
'lome' enclosing 'ones' is 'LONESOME'.
(Other definitions for lonesome that I've seen before include "Sole" , "Isolated" , "Sad and lonely" , "On one's own" , "Solitary and sad" .)
