lateralis

Forms

laterālis (neuter laterāle); third-declension two-termination adjective^[1]

Etymology

It is from Latin latus² (“side, flank”) + -ālis.^[2][3][1] De Vaan finds no good etymology for latus itself, an old s-stem.^[4]

Earliest recorded meaning

The first instance is lateralis dolor, “a pain in the side”, in a fragment quoted by Marius Victorinus,^[3][5] which Lewis & Short assign to Ennius^[3] and Conte and Köbler to Lucilius.^[6][7]

Semantic evolution

Lewis & Short call the adjective ante- and post-classical.^[3] Calpurnius has it of girths, and the Digest uses the neuter plural laterālia for saddlebags.^[3][5] Boethius made it a term of geometry.^[5]

In medieval Latin it meant “lying alongside, adjoining”, and also “of minor importance”; as a noun it named a companion or associate,^[8] courtiers in the plural, and a wife.^[9] Polish sources use it for collateral lines of kinship.^[10] English borrowed it as lateral in the early 15th century.^[11]
