- Thus hamburger (whose true etymology is 'city of Hamburg' + er 'someone from') has been reanalyzed as ham + burger 'burger made with ham.' [...] Subsequently, on the analogy of this folk etymology, new forms such as cheeseburger, chiliburger, and plain burger have been created.
- A modification of a word or its spelling resulting from such a misunderstanding, as with island, belfry, and hangnail.

- SURCEASE owes its form and meaning to a remarkable folk-etymology, as has been pointed out by Prof. Skeat:—"It is obvious, from the usual spelling, that this word is popularly supposed to be allied with cease, with which it has no etymological connexion."
