A pronoun is a word that takes the place of a noun. Examples: he, she, it, they, someone, who. Pronouns can do all of the things that nouns can do. They can be subjects, direct objects, indirect objects, object of the preposition, and more. Heck, the word pronoun even has the word noun in it! Let's look at a few examples.

Despite this formal training Rand found these institutes not stimulating and ultimately taught himself design, studying the works of A.M. Cassandre and Lazlo Moholy-Nagy through European magazines.
