I'm sure there is somebody about who knows more about Tolkien's elvish than I, like how to bend the gender of words to make doe from deer but I find no elvish word for doe or hind. I believe Arasaduial would be twilight(evening) deer, or Arasenaduial would be deer of twilight(evening) and Arasnuinithil would be deer under the moon. At least I believe those to be acurate in my limited understand of sindarin.
