Quenya
Tolkien almost never borrowed words directly from real languages into Quenya. The major exception is the name Earendel/Eärendil, which he found in an Old English poem by Cynewulf. Yet the Finnish influence extended sometimes also to the vocabulary. A few Quenya words, such as "tul-" "come" and "anta-" "give", clearly have a Finnish origin. Other forms that appear to have been borrowed are actually coincidental, such as Finnish "kirja" "book", and Quenya "cirya" "ship". Tolkien invented the Valarin/Quenderin root "kir-" from which sprang his Quenya word "cirya". The Latin "aure" "dawn", and Quenya "aure" "moment of special meaning, special day, festival day" are unrelated. Instead, Quenya "aurë" comes from the Valarin/Quenderin root ur-. Germanic influence can more be seen in grammar (the -r nominative plural ending is reminiscent of the Scandinavian languages) or phonology, than in words: "Arda", the Quenya name for "region", just happened to resemble Germanic "Erde" "earth", while it actually comes from the Valarin/Quenderin root "gar-". According to Tom DuBois and Scott Mellor, the name of Quenya itself may have been influenced by the name Kven, a language closely related to Finnish, but Tolkien never mentioned this.
