Etymology. The word lath is recorded from the late 13th century and is likely derived from the Old English word * læððe, a variant of lætt.This in turn would seem to stem from a Proto-Germanic word *laþþo, from which have sprung words in many Germanic languages, e.g. Dutch lat, German Latte.The root has also found its way into Romance languages, cf. Italian latta, French latte.
