The word **鹌鹑** (ānchún), meaning "quail," is a disyllabic, single-morpheme word formed through the combination of two phonetically and semantically linked characters, 鹌 and 鹑. Both characters are **semantic-phonetic compounds** sharing the bird radical **鸟 (niǎo)**, which categorically indicates they are types of birds. The components **奄 (yǎn)** in 鹌 and **享 (xiǎng)** in 鹑 primarily serve as phonetic clues for their respective historical pronunciations, which have since evolved in modern Mandarin. Together, they form an inseparable, **binomial term** specifically coined to name this particular bird, with neither character carrying independent meaning related to the quail on its own.
