The Chinese word 乱来 (luànlái) is a compound verb formed through a common grammatical structure where the first character, 乱 (luàn), meaning "chaotic", "reckless", or "disorderly", functions as an adverbial modifier describing the manner of the action denoted by the second character, 来 (lái), which in this context means "to act" or "to proceed". Literally translating to "to come/act chaotically", the combination creates an idiomatic meaning of "to act recklessly", "to mess around", or "to do something without following rules or proper procedure". This formation follows the pattern of a verb-phrase where a stative adverb (乱) modifies a verb of action (来), resulting in a new, specific lexical unit with a meaning greater than the sum of its parts.
