According to the Tattvarthasutra, the term "word" can be interpreted differently based on its etymology, and it states that one who adorns with royal insignia is a king, one who protects human beings is a ruler, and one who maintains and promotes the earth is a sovereign. The consideration of different meanings according to etymology based on these three names is referred to as "sambhirudhanaya." All interpretations of meaning created by variations of terms fall within this category of reasoning.
A deeper and more nuanced intellect now delves into the ultimate depth, asserting that when meaning differences are based on etymological distinctions, it should also be understood that one should only accept and express that meaning through that word when the etymological derivation of that meaning is valid; otherwise, it should not. According to this concept, possessing the capability of royal insignia or bearing the responsibility of human protection is not enough to be called a "king" or a "ruler." Moreover, when one genuinely wields the scepter and brings forth glory, and when human beings are indeed protected, only then can one be referred to as a king or ruler; that is, the terms "king" and "ruler" are applicable only in such a context. Likewise, a servant can only be referred to by that name while genuinely engaged in some service; the specific adjective or designation relating to that role should only be used when the actual task is being performed. This kind of understanding falls within the category of valid reasoning.
