The word "眼睑" is formed by combining the character "眼", meaning "eye", which originates from a pictographic representation of an eye, with the character "睑", meaning "eyelid", which is constructed from the semantic radical "目" (eye) to indicate its category and the phonetic component "佥" to approximate its sound. This combination results in a compound term that directly specifies the anatomical part known as the eyelid.
