hài đồng

hài đồng is a Vietnamese noun for an infant, baby, or very young child, but it does not sound like the everyday words you would usually hear in casual speech. Its tone is literary, poetic, formal, or old-fashioned, often carrying a feeling of innocence and tenderness. In this lesson, we look at why hài đồng feels different from common choices like em bé, trẻ sơ sinh, and trẻ nhỏ, and how it appears in phrases such as tuổi hài đồng or Chúa Hài Đồng. Watch the full lesson to learn when this gentle, classical word fits naturally.
