How to use "otherwise"

What Does "otherwise" Mean?

• Grammatical function: "Otherwise" primarily functions as a conjunctive adverb to indicate a negative condition or consequence (meaning "if not" or "else"). It also acts as an adverb of manner meaning "in a different way" and as an adjective to describe a state that is different from what has been mentioned.
• Typical sentence position: It is highly versatile and can appear in the initial position (starting a sentence), medial position (often between a subject and verb or following a semicolon), or final position.
• Register: It is generally neutral to formal, making it suitable for academic, journalistic, and professional contexts.

How to Use It

• Syntactic patterns: When used to show consequence, it typically follows a statement of requirement or fact. As an adjective, it often follows a noun it modifies (e.g., "the otherwise quiet room").
• Punctuation rules: When connecting two independent clauses, it should be preceded by a semicolon and followed by a comma. If it starts a new sentence, it is followed by a comma.
• Grammatical flexibility: It can be moved within a sentence for emphasis and can be used in phrases like "or otherwise" to cover all other possibilities.
• What sounds unnatural or incorrect: Using "otherwise" as a direct conjunction (like "and" or "but") without proper punctuation (a comma splice) is a frequent error in informal writing.
