@the_cecil_sol these are the sources i usually base off of for sindarin and quenya (which is another elvish language) ..
there are multiple great sindarin translator sites online and i love them
@the_cecil_sol not a lore dump but you've GOT to learn the languages because they are so interesting
my personal favorites are sindarin (type of elven language that mostly grey elves use), partly because of it's unique writing system and khuzdul which technically has words to it BUT i love it
