Examples:

“‘Toni Morrison: Sites of Memory,’ is an homage to the late Pulitzer Prize-winner, but also a walking meditation. The walls act as an altar—the writings, scripts, maps, drafts, letters and photos are thoughtfully placed assemblages that carry Morrison’s spirit. The author’s mellifluous voice, though subtle, echoes throughout the exhibition space, as an edited interview of Morrison at Boston College plays on repeat.” — Felice León, Essence, 2 Mar. 2023

Did you know?

Have a bee in your bonnet to learn some mellifluous facts? Sweet—we won’t make you comb for them. Mellifluous comes from two Latin roots: the noun mel, meaning “honey,” and the verb fluere, meaning “to flow.” These linguistic components flowed smoothly together into the Late Latin word mellifluus, then continued on into the Middle English word mellyfluous, before crystallizing into the adjective we employ today. As it has for centuries, mellifluous typically and figuratively describes sound, and is often at the tip of the tongues of writers who proclaim that a voice or melody is smooth like molasses (molasses, like mellifluous, is a descendant of the Latin mel). But mellifluous can also be used to describe edibles and potables, such as wine, with a pronounced note of sweetness.
