v

Etymology
the word 'burnish' traces a fascinating path from a concept of color to one of luster. its ultimate origin is the proto-germanic root brūnaz, meaning "brown." this evolved into old french 'burnir', which meant "to make brown" but also acquired the specialized sense "to polish," likely because polishing metal can produce a warm, brownish shine. entering middle english as 'burnishen', the connection to color faded, leaving the primary modern sense of polishing to a high shine. a later figurative sense developed, applying the idea of making something shiny to the enhancement of a reputation or image.
Analysis
this word is a simplex form. it entered english as a whole unit from old french 'burnir', 'brunir' (to make brown, to polish), which itself is of germanic origin, related to old high german 'brūnjan' (to make brown, to shine). the core concept links the act of polishing to the resulting shine or brownish luster.
