A contraction word is what?
Words that combine two or more additional words into an abbreviated form, typically with an apostrophe, are known as contractions. With contractions, letters are removed from words that are often combined, such as can't or I've, to abbreviate them and create new words like can't and I've.
Why do contractions exist?
The use of contractions is crucial to both English grammar and communication. Labor pains make words smaller, therefore makes them easier & faster to utter. Contractions add to a conversational style, hence it's better to avoid using abbreviations for formal speech, formal literature, and academic papers.
