this whole sentence taken from tutorial makes me wanna puke:
Viruses also known as virii, the latin plural are a means to get HPD different from missions.
1st: theres no such word "virii" in any language in the world, correct plural form in english is, unsurprisingly, "viruses"
2nd theres no plural for "virus" in latin
3rd the comma is redundant - you can place comma on
both sides of an inclusion or no commas at all, but placing only one is incorrect (not sure if this rule applies in english too)
4th
"are a means" omfg who wrote that? and how drunk he was then?
