Identify the pronouns in the biography by typing possessive, subjective, objective, intensive, or reflexive next to each pronoun.
Ambrose Bierce was a journalist. Many of his (possessive) newspaper columns focused on corruption, fraud, and people Bierce didn't like. Bierce had a biting wit, so people did not want to find themselves (reflective) the subject of one of his (possessive) columns. However, he (subjective) also had a very serious side to his writing. In fact, Bierce was disappointed with the war reporting of his (possessive) day, so he basically said, "I will do it myself (intensive) !" At the age of 71, he (subjective) rode alongside Pancho Villa's army as he (subjective) waged revolution across Mexico.
This is the best way to identify the pronouns found in this passage. In English, a pronoun is a word that takes the place of a noun. A noun is a word that is used to identify a thing or a set of things (living creatures, objects, places, actions, qualities, states of existence, or ideas). Pronouns are often used in order to avoid repeating a noun used previously.
