The meaning of part of speech:
In a language, many words that have the same syntactic function and can appear in the same combination position are aggregated to form a category. Part of speech is the most common grammatical aggregation.
The division of parts of speech is hierarchical. For example, in Chinese, words can be divided into content words and function words. Content words include body words and predicates, and body words can be divided into nouns and pronouns.
