"Why" is used to ask for reasons or explanations, whereas "because" is used to provide those reasons or explanations.
Key Differences
"Why" initiates a question seeking understanding or clarification, probing into the cause or reason behind an action or situation. "Because" is used in responses to convey the reason or rationale for something that has been questioned or stated.
In communication, "why" often expresses curiosity or a need for justification, prompting an explanatory response. "Because" serves as a bridge in conversation, linking an inquiry with its corresponding explanation or justification.
"Why" is typically used at the beginning of interrogative sentences, signaling a question. "Because" generally appears in the middle of declarative sentences, providing a cause or a basis for a statement.
In terms of grammar, "why" is an adverb or a conjunction introducing a question. "Because" functions as a conjunction connecting clauses, indicating a cause-and-effect relationship.
"Why" can also express a challenge or objection, seeking the rationale behind a decision or opinion. "Because" is used to affirm or defend a position, offering reasoning that supports a preceding statement or action.
