Language/Volapuk/Grammar/Or

Or is the polite word for ‘you’ and is used to address people formally; however, for one child, one relative, or people with whom you are on familiar terms, as well as animals, use ol. Ors is the plural of or and ols the plural of ol. In modern Volapük, however, the familiar word for ‘you’ (ol/ols) is generally preferred; it all depends on you, the user!
