Etymology: Latin "quattuor" is the ancestor of the English word "four," though the link is less direct than it looks. Its root reached English through the Germanic branch, giving Old English "fēower," while the Latin form passed into English through a different route, most visibly in words like "quartet" and "quatrain," which entered via Italian and French. Both descend from the same Proto-Indo-European number, which is why the Latin and English words resemble each other so closely despite arriving by separate paths. The Latin word is itself a fairly stable survival. Its neighbors in the Indo-European family, such as Greek "tessares" and Sanskrit "catvāras," show the same underlying sound pattern, so Latin "quattuor" preserves the older "qu" form that Latin later simplified in many other words. The "quattuor" family also gave English "quarter," a fourth part, and "quart," a fourth of a gallon, both showing how a counting word became a unit of measure.
