Hey, I've noticed a lot more elves lately and that's awesome! I thought some may appreciate a couple forgotten realms resources. I've personally adopted some of these sayings and such for my own character. This way you can avoid certain Lord of the Rings-isms like "vedui" or "edan"
http://www.candlekeep.com/library/articles/diction_elf.htm - This is a collection of various elven words and sayings collected by someone on the candlekeep forum, I believe. It is, as far as I'm aware, fairly old but mostly legit.
http://freepdfhosting.com/5f6a747504.pdf - This is the most complete collection of Forgotten Realms Elvish I've ever come across. While it's still woefully inadequate for a written language, it does contain words, phrases and places scoured from a good many official source books. It also features an english to elvish dictionary in the back half, meaning you can fairly quickly look up elvish for human if the need ever strikes you. It also teaches you how to form Espruar sentences if you're a crazy person.
http://www.fontspace.com/pixel-sagas/eladrin - This is one of several Espruar (the elven language in the forgotten realms, maybe D&D in general?) fonts. Use it for weird art things, I guess!
I hope this helps!
I've been looking for more resources on this, thanks for sharing!!
Found this one as well, not sure how accurate it is, but it has some useful phrases. http://www.grey-company.org/Circle/language/phrase.htm#greetings
That looks to be mostly entirely Lord of the Ring's Elvish, unfortunately.
