What is hence why?

Hence why is generally considered incorrect and redundant. It combines two similar phrases with overlapping meanings, resulting in an awkward and often grammatically flawed sentence.

• "Hence" means "for this reason" or "therefore". Link: https://www.wikiwhat.page/kavramlar/Hence

• "Why" implies a reason or cause. Link: https://www.wikiwhat.page/kavramlar/Why

Using them together essentially says "for this reason, why," which is semantically repetitive. Instead of using "hence why," it's better to choose either "hence" or "why," or to rephrase the sentence for clarity.

Examples of correct usage:

• Correct: "The equipment malfunctioned; hence, the delay." (Uses "hence" correctly.)
• Correct: "Why was the project delayed?" (Uses "why" correctly.)
• Correct: "The equipment malfunctioned. That is why there was a delay." (Rephrased for clarity.)

In summary: Avoid using "hence why" in formal writing or speech. Choose a more concise and grammatically sound alternative.
