The word "empirical" traces back to the Greek word empeirikos (ἐμπειρικός), derived from empeiria (ἐμπειρία), meaning "experience." The morpheme "empir" reflects this Greek root, while the suffix "-ical" (from Latin -icalis) forms an adjective. Originally used in medicine to describe knowledge gained from practical experience (as opposed to theoretical study), the term evolved in the 17th century to denote scientific methods grounded in observable evidence.
