An article is a word used with a noun to indicate what type of reference is being made. There are two types of articles: definite and indefinite. The definite article "the" refers to something specific, while the indefinite articles "a" and "an" refer to something unspecific. Articles go before adjectives and indefinite articles are only used with singular nouns. To write an article, you choose a topic, conduct research and interviews, outline the article, write a draft with an engaging opening and quotes, and finalize it with accuracy checks before the deadline.
