What are the parts of speech in English? When are words such as prepositions and nouns used? What do they mean?

1. Nouns

Words that express the names of people, things, places, phenomena or abstract concepts are called nouns. Nouns can be divided into proper nouns and common nouns.

Nouns can serve as any component in a sentence except the predicate, that is, subject, slogan, object (verb object and preposition object), adverbial, object complement, attributive, etc.

For example, table, stool, chair, sofa, table

2. Article

The article is a function word. It has no meaning and cannot be used alone. Used before a noun to help indicate the meaning of the noun. There are only three articles, namely the definite article (the) and the indefinite article (a, an)

I cannot give examples because they have no meaning

3. Numerals< /p>

Words that express numbers are called numerals. Numerals can be divided into cardinal numerals and ordinal numerals.

Numbers can be used as subjects, objects, attributives, predicates and appositives in sentences (appositives are limited to cardinal numerals)

Examples 1, 2, 3, 1st, Second, third

4. Pronoun

A pronoun is a part of speech that replaces a noun. Most pronouns function as nouns and adjectives. Pronouns in English are divided into eight types according to their meanings, characteristics and functions in sentences: personal pronouns, possessive pronouns, demonstrative pronouns, self-pronouns, mutual pronouns, interrogative pronouns, relative pronouns and indefinite pronouns

< p>Example me, you, his, myself

5. Adjectives

Adjectives modify nouns and describe the nature or characteristics of things/people. Generally, adjectives can be divided into two categories: qualitative adjectives and narrative adjectives. Their position is not necessarily in the noun

Adjectives can be used as predicates, attributives, object complements, and adverbials in sentences. It should be noted that as When an attributive modifies a noun, it should be placed in front of the noun. But if the adjective ends with -thing (such as something), it should be placed after these words

For example, small and big (the end of the word must be "的" when translated)

6. Adverbs

Adverbs, like describing something, also have the function of modification. Adjectives modify nouns, adverbs modify verbs, and adverbs can also modify adjectives and other adverbs. Adverbs modify verbs, adjectives, adverbs, or the entire sentence in a sentence. Used to express time, place, state, degree, etc.

Adverbs can be used as attributives, adverbials, predicates and object complements in sentences

For example, carefully, carefully (the end of the word must be "地" when translated)

< p>7. Preposition

A preposition is a function word. It cannot serve as a sentence component alone. It must form a prepositional phrase with a noun or pronoun or other part of speech, phrase or clause equivalent to a noun in order to serve as a sentence component< /p>

For example, in..., on...

8. Modal verbs

Modal verbs express the speaker's attitude towards a certain action and think it is "possible" , "necessary", etc. Modal verbs have word meanings, but the word meaning is incomplete. It must be followed by the infinitive of the verb "without to" (that is, the original form of the verb) (except "ought to"). In addition, modal verbs do not have number or person changes
