INTRODUCTION

English translation pending.

CORE DEFINITION

Four bodies and two functions is the arrangement of the six categories of script proposed by the Qing scholar Dai Zhen, who sorted pictograph, indicative, associative, and phonetic as the four bodies, the ways characters are coined, and mutual glossing and loan usage as the two functions, the ways existing characters are used. Its core proposition is that a writing system must be analyzed along two separate axes, how a character was made and how a word is used, and that confusing them garbles the philology. The key qualification is that the scheme is analytic, and the history of any real character may cross its lines.

SCAFFOLDING EFFECT

Reduce cognitive load

- Use axis separation: ask first whether the question is coinage or usage, and never mix the two. - Use body analysis: trace a character's form to its coined shape to reach its original meaning. - Use function analysis: follow the loan and extension to explain how the word is actually used.

Anchor fast decisions

A character's written form preserves the image its coinage was built on, while the word it writes has often traveled far from that image through loaning and extension. Reading the form alone tells you the original meaning and misses the current one, and reading the usage alone tells you the current one and misses why the shape looks as it does. The two axes together are what make both the form and the usage legible at the same time.
