Etymology
From sub- (“beneath, under”) + liminal (“of or pertaining to an entrance or threshold”) (from Latin līminālis, from līmen (“doorstep, threshold; doorway, entrance; beginning, commencement”); possibly ultimately from Proto-Indo-European *Heh₃l- (“to bend, bow; elbow”)) + *-mn̥ (suffix forming action nouns or result nouns from verbs)) + -ālis (suffix forming adjectives of relationship from nouns)). The noun is derived from the adjective.
The English word is a borrowing from German subliminal or a calque of German unterschwellig (“subliminal”, literally “beneath the threshold”).
