How to use "hence"

What Does "hence" Mean?

• Grammatical function: Hence expresses a cause-and-effect relationship, indicating that something is a consequence or result of what has been previously stated. It signals deduction and logical inference.
• Typical sentence position: Initial or medial
• Register: Formal

How to Use It

• Syntactic patterns: Hence is often followed by a comma when it begins a clause. It can connect two independent clauses, in which case it is usually preceded by a semicolon. It can also be used mid-clause, often set off by commas.
• Punctuation rules: A comma usually follows hence when it starts a clause. A semicolon often precedes it when linking independent clauses.
• Grammatical flexibility: Hence can start a sentence or appear mid-clause. It cannot be negated (e.g., "not hence" is incorrect).
• What sounds unnatural or incorrect: Using hence in very informal contexts can sound stilted. Avoid using it in casual conversation. Also, using it to introduce a completely unrelated idea is incorrect.

How can I avoid sounding too formal when using consequence connectives?

If you want to avoid sounding too formal, especially in spoken English or informal writing, consider using alternatives like "so," "that's why," or "as a result."
