Ever since I read LOTR I got interested in the Elvish languages! Your videos really expanded on a few phrases and words, and I'm thankful for that. I just hope one day, it will be a real and complete language
You are talking about Neo-Sindarin and Neo-Quenya. They exist, although, as far as I know (I'm not sure about it), they are not complete yet. But these are not actually Sindarin and Quenya. They are like expansions of both languages, with many words and expressions created by Elvish scholars and fans, and not by Tolkien. So they are not actually Sindarin and Quenya. Not my thing.
