3. Commendatory words, derogatory words and neutral words: According to the emotional color of words, words can be divided into commendatory words, derogatory words and neutral words. Praise refers to words with positive feelings, such as "good" and "excellent"; A derogatory term refers to words with negative feelings, such as "bad" and "bad"; Neutral words refer to words that have no obvious emotional color, such as "yes" and "no".
4. Simple words and compound words: According to the way words are formed, words can be divided into simple words and compound words. Simple words are words composed of one morpheme, such as "person" and "water". Compound words are words composed of two or more morphemes, such as "person" and "computer".
5. Open and closed categories: According to the way and quantity of words, words can be divided into open and closed categories. There are a large number of open words, which can constantly produce new words, such as surnames and place names in Chinese.

Differences between words:
1, different definitions: a word is the smallest grammatical unit composed of morphemes that can independently act as sentence components, and it is also an ancient form of poetry. Words, including words and phrases, are the general names of all words in a language.
2. Different scope: The scope of a word is larger than that of a word, which contains more language elements, including meaning, grammatical function, part of speech, pragmatics and so on. For example, the word "nice clothes" not only means "clothes", but also includes the adjective "nice" and the auxiliary word "de", which is a phrase grammatically.
