It's Merriam-Webster's Word of the Day for May 6.
Today's word is plangent, spelled P-L-A-N-G-E-N-T.
Plangent is an adjective.
Something such as a sound that is described as plangent is loud,
deep, and often expressive of sadness or suffering.
The word is a synonym of plaintive.
Here's the word used in a sentence from the New York Times by Giovanni Rusinello.
Adua sings in a keening, plangent tone, but at one point he pauses to offer a spoken invitation.
Listen to the wind, he says, the voice is calling you from yesterday.
Plangent adds power to our poetry and prose, the pounding of waves,
the beat of wings, the tolling of a bell,
the throbbing of the human heart,
a lover's knocking at the door, all have been described as plangent.
The word plangent traces back to the Latin verb plangaré, which has two meanings.
The first of those meanings, to strike or beat,
was sometimes used by Latin speakers in reference to striking one's breast in grief.
This led to the verb's second meaning, to lament.
The sense division carried over to the Latin adjective plenghens and then into English,
giving us two distinct meanings of plangent.
pounding as in the plangent roar of waves, and expressive of woe, grief, or melancholy.
