‘哼唧’ (hēng jī) is a reduplicated onomatopoeic word that imitates the sound of soft, repetitive whining or whimpering—often expressing mild discomfort, complaint, or petulance without full-blown crying. The first character 哼 (hēng) conveys nasal, grunting sounds (like sighing or protesting), while 唧 (jī) adds a light, high-pitched, repetitive quality, reinforcing the sense of fussy, low-volume vocalization. Together, they form a vivid, informal expression used mainly in spoken Chinese.

This term is commonly applied to babies, young children, or even pets (e.g., a restless puppy) making such sounds—typically when tired, hungry, hurt, or seeking attention. It carries a gentle, slightly affectionate or teasing tone rather than harsh judgment; it’s rarely used for serious distress. Though grammatically flexible, ‘哼唧’ most often functions as a verb (e.g., ‘宝宝在哼唧’) or a noun (e.g., ‘听这哼唧声’), and it’s almost always used in colloquial, intimate contexts—not formal writing or speech.
