Etymology

The word "psychology" originates from Greek psyche (ψυχή), meaning "soul" or "mind," and -logia (-λογία), meaning "study of." Initially, psyche referred to the breath or life force in ancient Greek philosophy, later evolving to denote the mind or soul. The suffix -logy was adopted into Latin and later English to form nouns denoting fields of study. Combined, "psychology" literally means "the study of the mind," reflecting its focus on mental processes and behavior.
