Hey everyone! I am kind of new at this and I am still learning the 2nd declension nouns. Scrolling around on the web I see that Latin inscriptions use "V" where I would expect a "U" to be, like in the word "Dominus." I see it written as "dominvs." Can someone explain to me why they did this, under what circumstances they used this convention, and is it proper to do so? Thanks for the help! I am excited to learn a lot here.
