委实 is a literary and emphatic adverb meaning 'truly,' 'indeed,' or 'really'—used to strongly affirm a statement, often with a tone of sincerity, gravity, or mild surprise. Though composed of two characters—委 (wěi), which can mean 'to entrust' or carry connotations of 'genuineness' in classical usage, and 实 (shí), meaning 'real' or 'true'—the compound functions as a fixed expression with no literal compositional meaning in modern speech.

It appears most frequently in formal writing, literary texts, historical dramas, or elevated spoken language (e.g., speeches, essays, or solemn declarations). Unlike colloquial intensifiers like 真 (zhēn) or 确实 (quèshí), 委实 carries stylistic weight and signals rhetorical emphasis rather than casual affirmation. It rarely occurs in everyday conversation among young speakers and may sound archaic or deliberately refined when used orally.
