What is an etymological definition of logic?

The word "logic" comes from the Greek word λογική (logikē), which is the feminine form of λογικός (logikos), meaning "relating to the word or thought." This, in turn, is derived from λόγος (logos), which has a wide range of meanings, including:

* Word, speech, discourse: This is the most basic meaning, reflecting how logic was initially seen as the study of language and its use in reasoning.

* Reason, thought, intellect: This sense reflects the development of logic as a formal system for analyzing and constructing arguments.

* Principle, order, rule: This meaning emphasizes the role of logic in identifying and applying principles of reasoning.

* Meaning, significance, explanation: This aspect underscores the goal of logic to clarify and explain the world through reasoned understanding.

Therefore, the etymological definition of "logic" points to its origins in the study of language and thought, focusing on the process of reasoning, the application of principles, and the search for meaning and explanation.
