The Chinese word **趁机** (chènjī) is a compound verb formed through a classic verb-object (动宾) grammatical structure. It combines the verb **趁** (chèn), meaning "to take advantage of" or "to seize," with the object **机** (jī), a shorthand for **机会** (jīhuì), meaning "opportunity." Literally, it parses as "to seize the opportunity," but its conventional meaning has evolved into the more specific and idiomatic sense of **"to seize the chance (often when someone is distracted or in a vulnerable moment)"** or "to exploit a situation." The formation is logical and transparent, where the object clarifies what is being taken advantage of, resulting in a word that effectively conveys the action of acting at an opportune, and sometimes covert, moment.
