lamentation

Etymology

Recorded since 1375, from 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. Lament is a 16th-century back-formation.

But Marin persists, and what ebullience and good humour, in the rocky ungentle loam? 1922 April, Paul Rosenfeld, “The Water-Colours of John Marin: A Note on the Work of the First American Painter of the Day”, in John Peale Bishop, editor, Vanity Fair, volume 18, number 2, New York, N.Y.: Vanity Fair Publishing Company, →OCLC, page 48, column 2
