Common Contractions in English

Contractions are words that are made by shortening and combining two words and replacing certain letters with an apostrophe (').

The contraction of will not is a little different from the other contractions. It doesn't follow the same pattern and become willn't; instead, it is contracted to won't.

The reason being that won't is based on a much older form of the word will. Even though we use will now, we kept the contraction of the old word; probably because willn't is a little tricky to pronounce compared to won't.
