A prescriptive definition refers to a word or sentence, and its meaning can only be the meaning set by the author.

1, no matter how others interpret it, its meaning is unchanged and can only be the original intention of the author.

2. For example, the classical Chinese in Chinese textbooks has different meanings from modern words.

For example, the way to know may be a general term in classical Chinese, which has another meaning, but its meaning is different from that of modern way to know.

Second, descriptive definition is different from prescriptive definition.

1, the prescriptive definition means that a word can only have a prescribed meaning, and its meaning remains the same no matter what it is understood.

2. But descriptive definition refers to the description of a word. For example, what is century education? The description of it is a descriptive definition.

Three, programmatic definition is the combination of descriptive definition and prescriptive definition.

1, such as "education should/the value of education should", has a clear value orientation and is a programmatic definition.

2. Mainly emphasize what "education" is and what it should be.
