The word **全然** (quánrán) is formed as a compound adverb through the combination of the morpheme **全** (quán), meaning "entirely" or "completely," and the classical Chinese suffix **然** (rán), which functions similarly to "-ly" in English, turning adjectives or other words into adverbs indicating manner or state. Thus, **全然** literally translates to "in a complete manner" and is used to mean "totally," "utterly," or "at all," most commonly employed in negative contexts or for strong emphasis to modify verbs or entire clauses. Its structure exemplifies a standard pattern in Classical Chinese lexicon where *然* is appended to intensify the adverbial quality of the root character.
