Mellifluous:
Sweet or pleasant to hear. (of voice or words)
In Latin, mel means "honey" and fluere means "to flow." Those two linguistic components flow smoothly together in mellifluus (from Late Latin) and mellyfluous (from Middle English), the ancestors of mellifluous. The adjective these days typically applies to sound, as it has for centuries.
