The term logic is derived from the Greek word logos.12
In ancient Greek, logos possesses a variety of senses, including "reason," "discourse," "sentence," "rule," "ratio," "account," "rational principle," and "definition". The word evolved through the Greek logikē (the feminine form of logikos, meaning "of reason"), passed into Latin as logica, and later into Anglo-French and Middle English as logik.132
The diverse meanings associated with logos reflect the complexity of characterizing the nature and scope of logic itself, which is broadly defined as the study of the principles and criteria of valid inference and reasoning.12
