Exploring Subliminals and the Subconscious | What is a subliminal?
The word subliminal is composed of the prefix sub-, the root word limen, and the suffix -al. Sub means “below”. Limen is Latin for limit or threshold, and the suffix “al” means “referring to”. So the word “subliminal” means “referring to that which is below the threshold”. Below the threshold of what? Your conscious mind, of course.
