Marrow and brain (髓惱: the upper character [髓] is pronounced *s[ui]* + *[tian]* [suǐ]. The *Shuowen [jiezi]* says: "The fat within bone." It is classified under bone (骨) with *sui* (隨) abbreviated for phonetic value. The lower character [惱, for 腦] is pronounced *n[eng]* + *[l]ao* [nǎo]. The *Wenzi jilüe* says: "The solid substance within the head." This character has many corrupt forms: written with three *zhi* (止), with *yue* (月), with *kou* (口), with *hu* (忽), or with *shan* (山)—all are incorrect. The standard form in the *Shuowen [jiezi]* is classified under *bi* (匕) and *xin* (囟); *xin* is pronounced *x[in]* [xìn], meaning the top of the head; it is classified under *chuan* (巛), which depicts hair, while *bi* means adhering together; [甾-十+乂] is phonetic; [甾-十+乂] is pronounced *n[eng]* + *[l]ao* [nǎo], originally an ancient character).
