The story
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 English word is a borrowing from German subliminal or a calque of German unterschwellig (“subliminal”, literally “beneath the threshold”).
