>because it is the lingua franca of the world now
One of the characteristics I love about English the most is the wanton, shameless adoption of not just words but entire phrases into the lexicon. 'Frankish Tongue', nah lingua franca it is. 'long time no see' is another favorite example. Ungrammatical in English, direct word-for-word translation from Mandarin? Sure, come on in, the water's fine. No one bats an eye.
