exam
UK: ɪɡˈzæm | US: ɪɡˈzæm
n. a formal test of knowledge or ability in a subject or skill (short for "examination")
n. (informal) a detailed inspection or analysis
The word "exam" is a clipped form of "examination," which derives from Latin examinare ("to weigh, test, or examine"), itself from examen ("a means of weighing"). The root ex- means "out," and -amen relates to "taking" or "measuring." Over time, "examination" evolved in Middle English to mean "testing knowledge," and its abbreviation "exam" became common in informal and academic contexts by the 19th century.
