A contraction in writing is a shortened form of a group of words that combines two or more other words in a shortened form, usually with an apostrophe. Contractions are used in both written and oral communication, and they are a way to make your writing seem more conversational and have the reader feel included in the writing. Contractions can make the reader feel like you are talking directly to them and having a conversation. It helps make your writing appear uncomplicated for everyone to understand and make sense of. However, it is important to note that contractions are often considered inappropriate in formal writing, such as academic research papers, important business presentations, or in any situation where informal writing or speech would not make much sense. In such cases, it is best to avoid using contractions to maintain a more serious and formal tone in your writing.
