Etymology: Lactescens is a botanical and medical term meaning "exuding milky fluid," and it comes straight from Latin. It is the present participle of "lactescere," meaning "to turn to milk" or "to become milky," built from "lac" (milk) plus the inchoative suffix "-escere," which marks the beginning of a change of state. So the word describes a process as much as a condition: something that is becoming milky. The Latin root "lac" is one of those that appears across the European languages, giving English "lactic," "lactose," and "lactation," while the Greek cognate "galaktos" gives us "galaxy," the "milky" band of stars. Both point back to an ancient word for milk, so "lactescens" and "galaxy" are distant cousins. In English, the word is used mainly in botany and zoology, for plants such as spurges and milkweeds that ooze a white latex when cut. Its use in English is largely technical, and it is recorded mainly in scientific writing rather than in everyday speech.
