Etymology

From Middle English alynen, alinen (“copulate”), from Middle French aligner, from Old French alignier, from a- + lignier, from Latin lineare (“make straight or perpendicular”), from the noun linea (“line”), from līneus (“flaxen; flaxen [thing]”), from līnum (“flax”), likely ultimately from Proto-Indo-European *līnom (compare linen).
