Sometimes we say someone is “deep in thought.” But what does that really mean? It helps to use simile phrases that compare thinking to something else. These similes use words like “as” or “like” to show how thinking can look or feel. They make our words more fun and clear.
When people think hard, their faces might look serious. When ideas come fast, it can feel like a race. Similes help us talk about these moments.
