Using That That in a Sentence: A Complete Guide to Emphasis, Clarity, and Style
Every time you encounter the phrase “that that” in written or spoken English, it can feel a bit unusual. Worth adding: most native speakers use a single “that” without a second one, so the double form often signals a specific grammatical function—emphasis, contrast, or a subtle nuance that a single “that” would miss. Mastering using that that in a sentence not only sharpens your expressive range but also helps you avoid common errors that can confuse readers. This article breaks down the mechanics, provides practical examples, and offers a step‑by‑step approach so you can confidently incorporate that that where it adds value.
Understanding “That” in English
The word that is one of the most versatile parts of speech in English. It can serve as a demonstrative pronoun (“This is mine, that is yours”), a relative pronoun (“The book that I read was fascinating”), or a conjunction introducing a subordinate clause (“I know that she will arrive on time”). Because of its flexibility, that often appears at the start of a clause to point to something specific, to give a definition, or to connect ideas.
People argue about this. Here's where I land on it.
When you repeat that, you are intentionally layering the word for a particular effect. The first that typically functions as a demonstrative or relative pronoun, while the second that acts as a connector or intensifier. This duplication is rare but powerful, especially in formal or literary contexts.
When Does “That That” Appear?
The double that is not a grammatical error per se; it is a stylistic choice that can be found in several scenarios:
- Emphasis or Contrast – To highlight a specific point or to set up a contrast between two ideas.
- Redundancy for Clarity – In complex sentences where a single that might be ambiguous.
- Literary or Rhetorical Effect – Authors and speakers sometimes use “that that” to create rhythm, irony, or a memorable phrase.
1. Emphasis or Contrast
Example:
- I love that that you always stay up late to finish your projects.
Here, the second that reinforces the specific action being praised, making the statement more vivid.
2. Redundancy for Clarity
Example:
- The only person that that I trusted in the meeting was the new analyst.
The repetition removes any doubt about which person is being referenced, especially when the antecedent could be confused with another noun.
3. Literary or Rhetorical Effect
Example:
- She said, “That that man is a liar,” and the crowd gasped.
The phrase creates a dramatic pause and underscores the accusation.

If you want to add emphasis, follow these simple steps:
- Identify the key noun or idea you want to highlight.
- Insert the first “that” as a demonstrative or relative pronoun pointing to that noun.
- Add the second “that” right before the verb or clause that contains the emphasized information.
Template:
[That] [that] + [verb/phrase]
Example:
- I will never forget that that you stood up for me when everyone else stayed silent.
