About
As a phono-semantic compound, 咿 uses the mouth radical 口 on the left to indicate its connection to vocal sounds. The right component 伊 serves as the phonetic element, providing the pronunciation. The character is used to transcribe high-pitched noises, such as the squeak of a door, the creak of oars, or an infant's babbling. It functions solely as a phonetic representation of sounds, without carrying any abstract meaning.
