According to a famous paraphrase of a quote by James D. Nicoll, “English doesn’t borrow from other languages. English follows other languages down dark alleys, knocks them over, and goes through their pockets for loose grammar.” And loose vocabulary, we might add. Lexicographer and etymologist John Ayto has remarked that English is “an inveterate borrower from other languages.” It has been estimated that more than two-thirds of English vocabulary can be traced back to foreign loanwords.
Throughout its history, English has been shaped and enriched by words and phrases of French, Scandinavian, Italian, Latin, Greek, Spanish, German, Russian, Dutch, Yiddish, and Japanese origin. Some of these words have been “naturalized”. For example, we don’t stop to think that the “very English” word “kitchen” is ultimately derived from the Latin verb “coquere” (to cook), or that good old “anger” was originally borrowed from Old Norse and is also related to the Latin and ancient Greek verbs for “strangle.
