Mind Magic: Sub vs. Un

Subconscious vs Unconscious

These words, “subconscious” and “unconscious,” are often confusing. Both are from the mind, but they mean different things. Here, we will learn their history, how to use them, and a trick to remember the difference.

History

The word “subconscious” is made up of “sub-” (meaning under) and “conscious” (meaning aware). It means the part of the mind that works below our awareness. People started using this word in the late 19th century.

The word “unconscious” is made up of “un-” (meaning not) and “conscious” (meaning aware). It means the part of the mind that we are not aware of at all. People started using this word in the early 18th century.

How to Use Them

Use “subconscious” to talk about feelings or thoughts that are just below the surface. You are not fully aware of them, but they still affect you.

Use “unconscious” to talk about things you are not aware of at all. It can also mean being knocked out or asleep.

Trick to Remember the Difference

Think of “sub” in “subconscious” as “under.” It means things are just under your awareness. For “unconscious,” think of “un-” as “not.” It means you are not aware at all.

Examples for Subconscious

Summary

“Subconscious” means the thoughts and feelings just below your awareness. “Unconscious” means you are not aware at all. Remember: “sub” means under, and “un-” means not. Use these words to describe different levels of awareness in the mind.
