subliminal
UK: sʌbˈlɪmɪnəl | US: sʌbˈlɪmɪnəl
adj. below the threshold of conscious perception; affecting the mind unconsciously.
The word "subliminal" originates from Latin sub (under) + limen (threshold), literally meaning "below the threshold." It was first used in psychology to describe stimuli perceived unconsciously. The root limin appears in related words like "liminal" (at a boundary) and "eliminate" (to push beyond a threshold). The term reflects the idea of hidden influence, as if slipping beneath the "doorway" of conscious awareness.
