subliminal
sub-LIM-ih-nul
/sʌbˈlɪmɪnl/
Below the threshold of conscious awareness or sensory perception.
Describes stimuli strong enough to affect the subconscious mind or physiological responses, yet too weak or brief for conscious awareness.
The story behind the word. Coined by 19th-century German psychologists from Latin 'sub-' (under) and 'limen' (threshold, doorway). It literally means 'under the doorway of consciousness'—a stimulus that doesn't step over the threshold into awareness.
Word relationships
- subconscious: 'Subconscious' refers to mental contents or states below awareness, whereas 'subliminal' specifically describes external stimuli designed to bypass conscious detection.
- imperceptible: 'Imperceptible' means completely undetectable, whereas 'subliminal' implies the stimulus still registers registered subconsciously.
- supraliminal: 'Supraliminal' explicitly means above the threshold of conscious awareness.
- conscious: 'Conscious' refers to active, explicit mental awareness.
