About
As a phono-semantic compound, 唿 combines the semantic radical 口 (mouth) on the left, indicating a connection to oral sounds or actions, with the phonetic component 忽 on the right, which provides the pronunciation "hu". The character primarily describes a sharp whistling sound or the act of blowing air to create an auditory signal. It is often used as an onomatopoeia in literature to represent sounds like rushing wind, swift movement through air, or a sudden exhalation.
