For, definitions, as has been said, being only the explaining of one word by several others, so that the meaning or idea it stands for may be certainly known; languages are not always so made according to the rules of logic, that every term can have its signification exactly and clearly expressed by two others.
Zeren, esan den bezala, definizioa hitz bat beste hitz batzuez azaltzea besterik ez denez gero, hitz horrek ordezkatu nahi duen ideia ziurtasunez ezagutu ahal izateko, hizkuntzak ez dira beti logikaren arauen arabera eratuak halako moldez, non hitz bakoitzaren esanahia beste bi hitzek adieraz dezaketen zehatz eta argi.
