多么 (duō me) is an adverb used exclusively in exclamatory sentences to express strong emotion—such as admiration, surprise, sorrow, or delight—and corresponds to English 'how' or 'what a(n)' at the beginning of an exclamation. It always precedes an adjective, noun, or verb phrase and cannot stand alone or appear in neutral statements or questions. Though written as two characters, 多 and 么, they function as a fixed grammatical unit: 多 contributes the core meaning of 'how much', while 么 is a grammatical particle that softens and intensifies the expression, turning it into an exclamatory marker.

This word is common in both spoken and written Chinese, especially in literary, poetic, or emotionally charged contexts—like praising beauty, lamenting loss, or marveling at nature. It’s frequently paired with adjectives (e.g., 多么美丽), nouns (e.g., 多么伟大的科学家), or verbs (e.g., 多么令人感动). Unlike English 'how', 多么 never appears before comparative structures or in subordinate clauses—it only introduces standalone exclamations.
