The Chinese word **器械** is a compound term formed by combining two characters with related meanings. The first character, **器** (qì), broadly means "utensil," "tool," or "vessel." The second character, **械** (xiè), specifically denotes "mechanical device," "instrument," or "apparatus." When combined, they create a binominal or coordinative compound where both elements reinforce and narrow each other's meaning, resulting in a comprehensive term that refers to "equipment," "apparatus," or "instruments," often implying mechanical or specialized tools used in fields like medicine, sports, or engineering.
