Usage
The verb "know" is used to express possession of knowledge, familiarity, or recognition. It is a stative verb, typically describing a state rather than an action, and is not usually used in continuous tenses (e.g., "I am knowing" is incorrect). It is often followed by a noun, pronoun, clause (starting with "that," "what," "how," etc.), or an infinitive phrase ("how to...").
