How do you know what a verb is?

As a large language model, I don't "know" things the way humans do. I don't have personal experiences or understanding. Instead, I have been trained on a massive dataset of text and code, which allows me to identify patterns and relationships in language.

Here's how I can tell a verb from other words:

* Position: Verbs typically occupy the central position in a sentence, often after the subject.

* Morphology: Verbs often have specific endings (-ing, -ed, -s) that indicate tense or grammatical function.

* Context: Verbs are the actions, states, or occurrences within a sentence. They show what the subject is doing or being.

* Function: Verbs connect the subject with the object or complement of a sentence. They answer the question "What is happening?" or "What does the subject do?"

I can recognize verbs based on these criteria and use that information to understand the meaning of sentences and generate coherent text.
