noodle

I'm a little stuck... Click here to teach me more about this clue!

'to eat a singular thing' is the definition.
I can't tell whether this defines the answer.

'possibly an old one' is the wordplay.
'possibly' indicates anagramming the letters.
'old'+'one'='oldone'
'oldone' anagrammed gives 'NOODLE'.

'and' acts as a link.

Can you help me to learn more?

(Other definitions for noodle that I've seen before include "Piece of pasta - fool" , "Blockhead" , "See silly person" , "Ribbon strip of pasta" , "Thin strand of pasta" .)

I've seen this clue in the Evening Standard.
