What does staining mean?
Staining is the process of colouring, marking, or discolouring a surface. It commonly refers to applying wood stain, dye, paint, or another substance to an object, as in staining a table or piece of furniture. The word can also name the discoloured mark left by coffee, wine, ink, or another material. In a more figurative and formal sense, staining refers to damaging someone's reputation by associating them with something discreditable. As a verb, staining is the present participle of stain and is used in ongoing actions, such as “She is staining the shelves.” The word is useful because it covers both the deliberate colouring of materials and the accidental or figurative discolouring that leaves a lasting impression.

Where does staining come from?
The related English verb stain comes through Middle English from Old French stainer, meaning “to dye” or “to colour,” which developed from the Latin verb stainare, “to dye.” The precise ultimate origin of the Latin word is not entirely certain. The present-participle and gerund form staining follows the ordinary English pattern of adding -ing to the verb.
