The Chinese word 全速 (quán sù) is a compound formed by combining two distinct characters: 全 (quán), meaning "entire" or "full", and 速 (sù), meaning "speed". It follows a common grammatical structure in Mandarin known as a "modifier-head" or "attributive" compound, where the first character (全) acts as an adjective or adverbial modifier describing the second, core noun (速). Therefore, the literal formation is "full" modifying "speed", which together create the meaning "full speed" or "at top speed", functioning as an adverb to describe an action performed at maximum velocity.
