Best practice
Use "as-if" to introduce a clause that describes a hypothetical or unreal situation. For instance, "He acted "as-if" he didn't notice the mistake, but I could tell he was embarrassed."
Common error
Avoid using "like" in place of "as-if" when introducing a clause. "Like" is typically used to compare nouns or phrases, while "as-if" is used to introduce a hypothetical scenario. Incorrect: "He looked like he was going to cry." Correct: "He looked "as-if" he was going to cry."
