Formal writing includes the use of standard English, less use of personal pronouns, lack of slang terms and colloquial words, and more complex sentence structures. Formal writing often includes long sentences and it also follows a more structured approach where points are introduced, explained, and concluded clearly. They are also carefully planned, revised, and reviewed several times to ensure clarity.

Informal language includes the use of nonstandard English forms, shorter sentence structures, and colloquial vocabulary. When one chooses to write in either formal or informal style, it affects certain areas which include standard or nonstandard English, use of contractions, use of pronouns, and choice of vocabulary. In informal writing, sentences, as well as paragraphs, are shorter which is particularly true for internet content. Writers may also make points using incomplete sentences or ellipses.
