How to use contractions
Understand when it is appropriate to use a contraction.
From a technical standpoint, contractions are not necessary in written english. The grammatically correct way to write requires the full version of every word.
Contracting, or shortening words, should only be done for stylistic purposes and for specific types of writing. If you are writing something where you are " talking " directly to your reader, you may use contractions.
