The lowercase letters u and v — These letters have a common origin and were once written according to the location in the word rather than the sound. The v came first; the u originally had a loop extending to the left and was only used to start words. All other locations for either u or v were written with the latter. In Germany (especially southern Germany), Austria and Switzerland, lowercase u is often written with a horizontal stroke or swish over it ("ŭ", "ū", "ũ"), to distinguish it from n. (cf. German orthography#handwritten umlauts)
