Where all your Tolkien questions are answered!
A: Yes, he would, but probably not for a while. He was a great king of the Noldor, but he did go to Middle-Earth against the wishes of the Valar, and he and his people were involved in the first Kinslaying at Alqualonde. When the elves die and their spirits go to the Halls of Waiting, or the Halls of Mandos, they are judged by their deeds in life, and given a choice, for reincarnation is optional. If they choose to be reincarnated they have to wait for a certain amount of time, probably thousands of years in our measurement. But yes, I suspect he probably would have been reincarnated at some time--if he wished it.
Q: What does "Namarie" mean?
A: It means "Farewell" in Sindarin, the common speech of the elves. There were several different languages the elves spoke in, just like in the world today, and also several variations of the same type of elvish. For example, American English and European English can differ quite a lot, though both are still pretty much understandable by someone coming from either culture. There were languages for the Nandor (called Nandorin), the Sindar (called Sindarin, but later on it because something like a "Common Tongue" that most elves spoke), and Quenya (it became a more arcane form of elvish, used in formal ceremonies and songs only, sort of like Elizibethian English is to us today). So to say "Farewell" in Sindarin is "Namarie" but in Quenyan it is "Namar."
Q: If Galadriel is Arwen's mother, how come she looks so young?
A: I would like to know that, too! What's your secret, milady? Seriously, the reason is because Elves do not age the same way humans do. When they reach the body type they will carry for the rest of their lives, usually when they're about fifty to one hundred years old, they change very little throughout their lives. A very good example would be to compare the movie Elrond to the movie Legolas. Legolas is, supposedly, about three thousand years old, and Elrond is about nine thousand years old. While both are still handsome (or should be) Elrond is obviously older than Legolas. While Legolas looks to be in his twenties, Elrond appears to be in his late thirties or early forties.
Q: How long do Ents live?
A: There is no direct reference to how long an Ent can live. However, since they came to be around the time the Elves appeared, they probably have similar lifespans. I.e, they can age, bot do not die naturally. Their skin is very tough, but it can be burned. Anyone who has more information on this can email me.
Q: Do Ents eat Orcs?
A: Possible, but doubtful. While they would kill orcs, orc-meat is not exactly the most appatizing of meals.
Q: What do Orcs eat?
A: They like blood and raw meat. Among other things they eat ponies, men, and their own kind.
Q: Can you get me a date with Elrohir?
A: Only if you get me one with Legolas.
