The study of the meaning of words in a particular language according to the semantic classification system is a branch of linguistics whose task is solely to examine the meaning of words, their origins, even how they developed, and the reasons for changes in meaning in the history of language. Many other fields of science are related to semantics, therefore meaning plays a role depending on the use of language as a tool for conveying mental experiences, thoughts and intentions in society. The field of semantics is limited to efforts to pay attention to and study the process of transposition of word meanings in language use. Ullman (1972) argues, if someone thinks about the meaning of a word, they simultaneously think about its reference or vice versa. The relationship between two things, meaning and words, is where meaning is born.

Epistemology in Philosophy, Epistemology comes from the Greek words, namely epistememe = knowledge and logos = words, thoughts, knowledge. Epistemology aims to critically examine the logical presuppositions and conditions that underlie the possibility of knowledge and tries to provide rational accountability for its claims to truth and objectivity. Rationalism is a philosophical ideology which states that reason is the most important tool for gaining knowledge and gaining knowledge. If empiricism says that knowledge is obtained by experiencing empirical objects, then rationalism teaches that knowledge is obtained by thinking. The tools in thinking are logical rules or logical rules.
