etymological

adj

1. (not-comparable)Of or relating to etymology.

   “But it goes without saying that this etymological argument in and of itself has no significance, since a word taken from a dead language may resultantly assume a meaning independent of its etymology.”

2. (comparable)Consistent with its etymological characteristics (in historical usage or the source language).

   ““Connexion” is the etymological (ie, “correct”) spelling. That is to say, our word is derived from an actual Latin noun, cf. deflexion, inflexion, and reflexion. […] And it might make life easier to abolish the letter “x”. But why should we cut off the fascinating roots of our words? I should carry on preferring “connexion”.”
