Glosa (auxiliary language)
Substantives here are the group of words that represents the more complex things, actions and descriptions (sometimes usable for all three) present in a language, such as: via [road], kurso [run], hedo [happy], vide [see], celera [swift], tako [fast; quick; prompt; hurry; rate; speed]; oku [eye].  Please note that many of these words have many meanings, based on how they are used in a sentence (verb, adjective, etc.), for example: "oku" can mean "eye", "optical", "see (look)", "perceive (with the eyes)", or "to peep".
