Left sailor with one old penny (9)
I believe the answer is:
abandoned
'left' is the definition.
(abandoning is a kind of leaving)
'sailor with one old penny' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'with' becomes 'and' (I've seen this before).
'old penny' becomes 'd'.
'ab'+'and'+'one'+'d'='ABANDONED'
(Other definitions for abandoned that I've seen before include "Deserted - shameless" , "Quit" , "Left - dissolute" , "Crazy!" , "Forsook, left behind" .)
