How

How is a question word (adverb) we use to ask about the way, method, or degree of something. For example, “How does this work?” or “How difficult is the test?” It can also show the state, condition, or manner of being (your health, feelings, or situation), as in “How are you?” Here how means in what condition you are. Sometimes, how works as a conjunction, which connects a clause (= statement) to show the way something happens. For example, “I don’t know how she solved the problem.” Here, “how she solved the problem” explains the method or manner of the action. People use “how” in both questions and explanations to learn about actions, feelings, or conditions.
