Question:

I don’t understand the difference between "look," "appear" and “seem." If I say, “His new haircut makes him appear younger,” is it correct? - Mika, Japan
Answer:

Hello Mika and thanks for your question!

You can use “appear” in that situation, but the better verb would be “look.”

Let me give you the reasons why.

Look

We use both the verbs “look” and “appear” to talk about a condition we have observed. In your sentence, you can see with your eyes how stylish the man’s new haircut is. You also see that it gives his face a more youthful shape.

But “look” is more informal than the verb “appear.” Your sentence sounded informal, as if you were talking to a friend.

Appear

In contrast, you might see the word “appear” in writing, or hear it in formal speech, such as an official news report. For example, a news reporter might say, “The suspect appeared to be fleeing the scene.”

As that example shows, “appear” is commonly used to talk about events and facts.

Seem

Your third choice, “seem” also means “to create an idea or impression.” But “seem” does not suggest a direct observation. For example, you and I may have talked on the phone, and you told me about your great new job and recent vacation. Afterward, I could say, “Mika seems happy,” even though I never saw you smile.

Take Note

Keep in mind one other difference among the three words. “Seem” and “appear” are often followed by an infinitive verb, such as “The baby seems to want her bottle…” or “The man appears to be waving.”

But, in everyday English, the verb “look” is often followed by an adjective. For example: “He looks tired.”
