Those which are not intelligible at all, such as names standing for any simple ideas which another has not organs or faculties to attain; as the names of colours to a blind man, or sounds to a deaf man, need not here be mentioned.
Inola ere ulergarriak ez diren hitzak ez dira hemen aipatu beharrekoak, hala nola, beste batek atzemateko organorik edo ahalmenik ez duelako ulertu ezin dituen ideiak ordezkatzen dituzten izenak, adibidez, koloreak itsuak edo soinuak gorrak.
