The phrase “which means” is one of the most useful transition tools in written English. It allows you to elaborate on a cause, explain a consequence, or clarify the practical result of a statement you just made.
However, because it begins with the relative pronoun “which,” writers frequently misuse it—often creating sentence fragments or using incorrect punctuation.
This guide breaks down the exact grammar rules for using “which means” correctly, complete with punctuation guidelines and real-world sentence examples.
Note: This guide expands upon the grammar rules discussed in theEnglish Forward ‘Which Means’ Forum Thread.
1. The Core Rule: “Which Means” Introduces a Dependent Clause
Grammatically, “which means” introduces a relative clause (or dependent clause). This means it cannot stand alone as a complete sentence because it relies on the main clause that comes before it.
Incorrect (Sentence Fragment):
- ❌ The train was delayed by two hours. Which means I missed my morning meeting.
Correct (Single Complete Sentence):
- The train was delayed by two hours*, which means I missed my morning meeting.*
In the correct example, the first part (“The train was delayed by two hours”) is an independent clause. The comma followed by “which means” connects the explanation directly to that main clause.
2. Proper Punctuation with “Which Means”
To use “which means” seamlessly in formal and professional writing, follow these punctuation structures:
Option A: Use a Comma Before “Which Means”
Place a comma directly before “which” when connecting it within the same sentence.
Formula:
[Independent Clause] + , which means + [Consequence/Result]
- Example: The office will be closed on Friday*, which means** all pending reports are due by Thursday afternoon.*
Option B: Use a Semicolon or Period with a Transition
If you want to start a brand-new sentence to emphasize the point, swap “which means” for “This means,” “That means,” or “As a result.”
Formula:
[Independent Clause]. + This means + [Consequence/Result]
- ❌ Incorrect: Demand for the product doubled. Which means we need to increase production.
- Correct: Demand for the product doubled*. This means** we need to increase production.*
- Correct: Demand for the product doubled*; this means** we need to increase production.*
3. Common Use Cases & Examples
Here is how to apply “which means” across different contexts:
Explaining Cause and Effect
- The software update includes automated backup capabilities, which means users no longer have to manually save their work.
Clarifying Technical or Complex Terms
- The property is sold under a share block scheme, which means buyers purchase equity shares rather than direct land title.
Outlining Workplace Guidelines
- All leave requests must be submitted 14 days in advance, which means late submissions will require manager approval.
4. Alternatives to “Which Means”
Varying your vocabulary keeps your writing engaging. Depending on your sentence structure, consider these professional alternatives:
| Alternative Phrase | Example Usage |
| “Meaning that…” | The contract expires in December, meaning that renegotiations must start soon. |
| “Which indicates that…” | Sales increased by 20%, which indicates that the campaign was successful. |
