πείραμα

Etymology: From ancient Greek πεῖρα (peira) meaning 'trial, attempt, experience' plus the suffix -μα (-ma) indicating result or product of action. The root πεῖρα is related to the verb πειράω (to try, attempt) and connects to English words like 'empirical' (from Greek empeiria, meaning experience gained through trial) and 'pirate' (originally 'one who attacks/tries'). The word emphasizes the systematic nature of testing hypotheses, distinguishing it from casual attempts.
