Its 1502 definitions attempt to establish semantic connections based upon puns between the word being defined and the word defining it, which is often followed with an explanation. For instance (chapter 12: 愛哀也愛乃思念之也), "Love (ài 愛 "love; like; be fond of") is sorrow (āi "哀 sorrow; grief; lament"). If you love, then you remember fondly." The Chinese call these paronomastic glosses yīnxùn (音訓; yin-hsün; "sound teaching"), meaning "to use the pronunciation of a word to explain its meaning." This semantic association of like-sounding words goes back to the "Rectification of Names" (zhèngmíng 正名, discussed under Confucianism), which hypothesized a connection between names and reality. The Shiming preface explains this ancient Chinese theory of language.
In the correspondence of name with reality, there is in each instance that which is right and proper. The common people use names every day, but they do not know the reasons why names are what they are. Therefore I have chosen to record names for heaven and earth, yin and yang, the four seasons, states, cities, vehicles, clothing and mourning ceremonies, up to and including the vessels commonly used by the people, and have discussed these terms with a view to explaining their origin. (tr. Miller 1993: 424)
