Why is their an apostrophe in s'mores?

The apostrophe in "s'mores" is a contraction that combines the Words "some" and "more." The apostrophe replaces the missing letters in the Word "some" (s-o-m-e), indicating that letters have been omitted for brevity and to indicate the combination of the two Words. It is a common practice in English to use apostrophes in contractions to show where letters have been removed.
