英语词汇pho的起源、历史背景-英语词源词典

词汇	pho
词源	pho n. type of Vietnamese soup, probably from French feu "fire" (see focus (n.)) "as in pot-au-feu, a stew of meat and vegetables of which the broth is drunk separately as a soup" [Ayto, "Diner's Dictionary"] which would have been acquired in Vietnamese during the French colonial period. Entries linking to pho focus n. 1640s, "point of convergence," from Latin focus "hearth, fireplace" (also, figuratively, "home, family"), which is of unknown origin. Used in post-classical times for "fire" itself; taken by Kepler (1604) in a mathematical sense for "point of convergence," perhaps on analogy of the burning point of a lens (the purely optical sense of the word may have existed before Kepler, but it is not recorded). Introduced into English 1650s by Hobbes. Sense transfer to "center of activity or energy" is first recorded 1796. updated on May 23, 2020
