Imbrown

Part of speech: verb

Definitions

1. To change the color of an object to brown or to fade into a brown shade while undergoing a transformation over time
2. To alter the appearance of an item so that it takes on a brown tone, indicating a shift in its color due to exposure or processes
3. To cause an object or surface to take on a brown hue, often through a chemical or physical process

Etymology: The word is an archaic spelling of "embrown", a verb built from the prefix "em-" (a variant of "en-", used to mean "bring to a certain condition or state") and the adjective "brown". So the core of it is simply "to make brown," and the sense of "embrowning" a person's legs by sun exposure is the kind of physical change the verb was made to describe. The same pattern appears in French "embrunir" and Italian "imbrunire", which are cognates built on the same idea of darkening or browning something. Those parallels show that the formation is not unique to English but shares a common approach to turning a colour adjective into a verb.
