What are pure verbs?

Pure verbs (also known as lexical verbs or full verbs) are a type of verb that has its own meaning, usually expressing an action or a state. On their own, they can convey a complete idea or form the core meaning of a sentence. They don't require any additional words to fully express their meaning, unlike auxiliary verbs or modal verbs.

Here are some examples of pure verbs:

- run

- jump

- read

- write

- think

- feel

- come

- go

- sleep

- play

- eat

Pure verbs can be used in various tenses (past, present, future), voices (active or passive), and moods (indicative, subjunctive, imperative) according to the context and grammatical rules.

For instance, consider the following sentence:

> "She is running in the park."

Here, "running" is a pure verb that expresses the action of the subject ("she") and fully communicates the main idea of the sentence.

Some pure verbs can have a broader or more general meaning, and thus can be followed by various complements (objects, adverbs, etc.) to provide additional information. For example:

> "They played soccer in the afternoon."

> "She felt excited about her new job."

> "The team won the championship trophy."

In these cases, the pure verbs "played," "felt," and "won" are complemented by prepositional phrases and object nouns to complete their meaning and offer more details about the situation.

In contrast to pure verbs, auxiliary verbs and modal verbs are not able to stand on their own to convey a complete thought. Auxiliary verbs assist main verbs in forming various grammatical structures, such as tenses and voices, while modal verbs express possibility, necessity, permission, or other modifications.

Pure verbs play a crucial role in constructing sentences by providing the core action or state being described, whereas auxiliary and modal verbs support them and add grammatical and contextual information.
