Common Eldarin split off Primitive Quendian, the original language of all Quendi, or Elves, when the Eldar left Cuiviénen for Valinor. As the years passed, the language of those Elves as they traveled, became a little different than the one spoken before the March.
Since the Eldar dominate the annals of the Elder Days, all the Elvish languages that appear, come from that branch. The Avarin languages possibly followed a wholly different evolution, outside Common Eldarin.
Evolution from Primitive Quendian
During the Great March, minor changes to the Primitive Quendian brought the later Eldarin languages. These changes had to do with several developments of the word-forms, usually normalization. For example:
- "Difficult" consonant clusters, usually those with nasals (like bm and dn), were rearranged
- PQ: labmâ (root LAB) > CE: lambâ
- PQ: stabnê (root STAB) > CE stambê
- Final short -a, -e, -o are lost, sometimes producing a long monosyllable as their trace
- PQ: ndêro > CE: ndæ^r (kwende > quendë is an exception)
- a infiction in some stems which produced new diphthongs like ae, ao
- PQ: *melâ (root MEL) > CE *maelâ
- final long -â, -ê, -î, -ô, -û became short (later stage)
- CE: stambê > stambe
- CE: mahtâ > mahta
- CE: lambâ > lamba
At some point, dialects separated the uniformity of that language, and produced the Common Telerin branch.
