Relative Pronouns

There are five relative pronouns in English: whowhomwhose, that, and which. These pronouns are used to connect different clauses together. For example:

  • Belen, who had starred in six plays before she turned seventeen, knew that she wanted to act on Broadway someday.
    • The word who connects the phrase “had starred in six plays before she turned seventeen” to the rest of the sentence.
  • My daughter wants to adopt the dog that doesn’t have a tail.
    • The word that connects the phrase “doesn’t have a tail” to the rest of the sentence.

These pronouns behave differently from the other categories we’ve seen. However, they are pronouns, and it’s important to learn how they work.

Two of the biggest confusions with these pronouns are that vs. which and who vs. whom. The two following videos help with these:

That vs. Which

Who vs. Whom

(1) Katerina, whom had taken biology once already, was still struggling to keep the steps of cellular respiration straight. (2) She knew the process took place in animals, which take in oxygen and put out carbon dioxide. (3) She also knew that plants underwent the process of photosynthesis. (4) However, the individual steps of the process seemed beyond her understanding.
