Chinese characters are primarily morphosyllabic, meaning that most Chinese morphemes are monosyllabic and are written with a single character, though in modern Chinese most words are disyllabic and dimorphemic, consisting of two syllables, each of which is a morpheme. In modern Chinese 10% of morphemes only occur as part of a given compound. However, a few morphemes are disyllabic, some of them dating back to Classical Chinese. Excluding foreign loan words, these are typically words for plants and small animals. They are usually written with a pair of phono-semantic compound characters sharing a common radical. Examples are 蝴蝶 húdié "butterfly" and 珊瑚 shānhú "coral". Note that the 蝴 hú of húdié and the 瑚 hú of shānhú have the same phonetic, 胡, but different radicals ("insect" and "jade", respectively). Neither exists as an independent morpheme except as a poetic abbreviation of the disyllabic word.
