Etymology

The word "plume" traces back to Latin pluma, meaning "feather" or "down." It entered Middle English via Old French plume, retaining its core meaning of a feather, often emphasizing elegance or display. Over time, it expanded to include decorative uses (e.g., plumed hats) and the grooming behavior of birds ("pluming" themselves). The morpheme remains intact, reflecting its direct Latin-French lineage without fragmentation.
