Ludwig's WRAP-UP

The phrase "that's undeniably true" is a high-impact linguistic tool used to concede or confirm factual accuracy with absolute certainty. According to Ludwig, it appears most frequently in high-quality journalism and scientific discourse, suggesting a strong association with evidence-based reasoning. Whether used to acknowledge a counter-argument or to bolster a claim, it signals intellectual honesty. Writers should be mindful of the difference between "that's" and "that is" to match the level of formality required, but the core effectiveness of the phrase remains its ability to close the door on doubt.

FAQs

How do I use "that's undeniably true" in a sentence?

You can use it as a standalone response or as a concessive clause, for example: "While "that's undeniably true" in some cases, the broader trend suggests otherwise."

What can I say instead of "that's undeniably true"?

Depending on the tone you want, you can use alternatives like "it's objectively the case", "that is certainly accurate", or "it's an indisputable fact".

Is it better to use "that's" or "it's"?

Both are correct, but ""that's undeniably true"" specifically refers to something previously mentioned by another person, whereas "it's undeniably true" can refer to a general concept.

Is the phrase formal enough for business writing?

Yes, though in very formal documents, you should expand the contraction to "that is undeniably true" to maintain a professional register.
