Left on one’s Tod? (4)
I believe the answer is:
lone
'left' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'on one's tod?' is the wordplay.
'on' is a charade indicator (letters next to each other).
'tod?' becomes 'l' (I am not sure about this - if you are sure you should believe this answer much more).
'one' after 'l' is 'LONE'.
Can you help me to learn more?
(Other definitions for lone that I've seen before include "Single and isolated" , "The ... Ranger, fictional masked cowboy" , "Solitary or single" , "Companionless" , "He likes to operate by himself" .)
