Thereby vs. Therefore: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 16, 2024
"Thereby" implies a method or means ("by that means"), while "therefore" indicates a conclusion or result ("for that reason").
Key Differences
"Thereby" is used to indicate the method or process by which something is achieved, implying 'by that means' or 'as a result of that'. "Therefore" is used to denote a conclusion, often used in the sense of 'for that reason' or 'consequently'.
In usage, "thereby" often introduces the means or cause of an action in a sentence. In contrast, "therefore" introduces a conclusion or result that follows logically from a previous statement.
"Thereby" is typically followed by a verb phrase, indicating the action through which the result is achieved. "Therefore" is usually followed by a comma and completes a thought, providing the logical result of the previous statement.
An example of "thereby" is: "He studied hard, thereby passing the exam." Here, it connects the action of studying to the result of passing. An example of "therefore" is: "It was raining, therefore the event was canceled," where it connects the condition of rain to the conclusion of canceling the event.
"Thereby" often relates to a direct consequence of an action, while "therefore" is more about deducing a conclusion or a reasoning outcome from a given set of facts or statements.
