‘吉言’ literally combines ‘吉’ (jí), meaning ‘auspicious’, ‘lucky’, or ‘propitious’, and ‘言’ (yán), meaning ‘words’, ‘speech’, or ‘saying’. Together, they form a formal, literary noun meaning ‘auspicious words’—that is, blessings, good wishes, or favorable sayings offered to bring luck, health, prosperity, or harmony. It is commonly used in ceremonial contexts such as weddings, Lunar New Year celebrations, birthdays, and housewarmings.

Unlike casual greetings like ‘恭喜发财’ (gōngxǐ fācái), ‘吉言’ carries a classical, respectful tone and often appears in written inscriptions, couplets, speeches, or ritual recitations. It may also appear in idioms or poetic expressions, emphasizing sincerity and cultural weight behind the words spoken. While not everyday conversational vocabulary, learners will encounter it in traditional festivals, formal invitations, and classical texts—making it valuable for understanding Chinese values around language, intention, and auspiciousness.
