The "Etymologies" has the form of a scholarly work listing the "bases" or "roots" of the protolanguage of the Elves: Common Eldarin and Primitive Quendian. Under each base, the next level of words (marked by an asterisk) are "conjectural", that is, not recorded by Elves or Men (it is not stated who wrote "The Etymologies" inside Middle-earth) but presumed to have existed in the proto-Elvish language. After these, actual words which did exist in the Elvish languages are presented. Words from the following Elvish languages are presented: Danian, Doriathrin (a dialect of Ilkorin), Eldarin (the proto-language of the Eldar), (Exilic) Noldorin, Ilkorin, Lindarin (a dialect of Quenya), Old Noldorin, Primitive Quendian (the oldest proto-language), Qenya, Telerin.
