Singular nonsense from the shoemaker (7)

I believe the answer is:

cobbler

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

'the shoemaker' is the definition.
('cobbler' can be a synonym of 'shoemaker')

I can't explain the rest of the clue.

(Other definitions for cobbler that I've seen before include "snob" , "Shoemaker and repairer" , "one getting down to work at last?" , "An iced drink; a mender" , "Mender of boots and shoes" .)

I've seen this clue in the Evening Standard.
