To feed starving mutt, this woman's focus — there's nothing from table (6,7)
I believe the answer is:
mother hubbard
'to feed starving mutt this' is the definition.
The definition suggests a singular noun which matches the answer.
'woman's focus there's nothing from table' is the wordplay.
I cannot quite understand how this works, but
'woman's' could be 'her' (belonging to a woman) and 'her' is found in the answer.
'focus' could be 'hub' (I've seen this in another clue) and 'hub' is present in the answer.
'nothing' could be 'o' (looks like zero - 0) and 'o' is found within the answer.
'table' could be 'bar' (bar is a kind of table) and 'bar' is present in the answer.
This explanation may well be incorrect...
