Linguist David Crystal describes English as a "vacuum cleaner of a language." Speakers merrily swipe some words from other languages, adopt others because they're cool or sound classy, and simply make up other terms.
In his new book, he tells The Story of English in 100 Words, using a collection of words — classic ones like "tea" and new words like "app" — that explain how the the English language has evolved.
Crystal thinks every word has a story to tell, even the ones as commonplace as "and."
