lamentation

Etymology

Recorded since 1375, from Middle English lamentacioun, from Middle French lamentation and its etymon Latin lāmentātiō (“wailing, moaning, weeping”), from the deponent verb lāmentor, from lāmentum (“wail; wailing”), itself from a Proto-Indo-European *leh₂- (“to howl”), presumed ultimately imitative. Replaced Old English cwiþan. By surface analysis, lament + -ation.
