As vs. Like

The words "as" and "like" are used to make comparisons, but they are used in different ways. 1. Use "like" when you want to compare two things that are similar. It is followed by a noun or pronoun. - Example: "She sings like a bird." (comparing her singing to a bird) 2. Use "as" when you want to show the role or function of something. It is often followed by a noun, but can also be followed by a clause (a subject and a verb). - Example: "She works as a teacher." (showing her job)
