The contraction for “that is” is “that’s,” used in everyday speech and informal writing.
What Is The Contraction For That Is? Brief Answer And Context
If you have ever paused over the question “what is the contraction for that is?”, you are not alone.
In standard English, the short form of “that is” is “that’s.” The apostrophe replaces the missing letter “i” in “is,” so “that is” becomes “that’s.” This pattern matches other common pairs such as “it is” → “it’s” and “she is” → “she’s.”
Spoken English uses “that’s” often because it is quick and natural. In writing, “that’s” appears in emails, texts, stories, and friendly articles, while “that is” tends to sound a little more formal or emphatic. Both forms are correct; the choice depends on tone, audience, and context.

How English Contractions Work In Simple Terms
To understand why “that’s” stands for “that is,” it helps to look at what contractions do in English. A contraction joins two words, drops one or more letters, and uses an apostrophe to mark the missing letters. The spoken form comes first; the written form tries to mirror the way people actually talk.
In school, many learners first meet contractions through pairs such as “do not” → “don’t” or “I am” → “I’m.” The same idea applies to “that is.” When you say the phrase out loud, the sounds blend together naturally, so “that is” slides into “that’s.” The apostrophe simply shows that blend on the page.
Not every pair of words forms a standard contraction, and some contractions stay informal. A common case is “gonna” for “going to,” which appears in song lyrics and dialogue but rarely in formal writing. By contrast, “that’s” is a normal contraction that appears in speech, stories, articles, and teaching materials across levels.
Why Writers Switch Between “That Is” And “That’s”
Writers shift between “that is” and “that’s” to manage tone and emphasis. “That is” slows the sentence and draws attention to the words that follow, so it often appears before definitions, clarifications, or contrast. “That’s” feels lighter and more conversational and keeps the sentence moving.
Look at these pairs:
- “That is the main idea of the paragraph.” (slightly more formal)
- “That’s the main idea of the paragraph.” (neutral, everyday tone)
- “That is what I meant to say.” (stronger stress on “is”)
- “That’s what I meant to say.” (smooth, spoken tone)
Both versions carry the same core meaning. The longer form places a bit more weight on the verb, while the contraction blends into the rhythm of the line.
Using The Contraction For That Is In Real Sentences
Once you answer “what is the contraction for that is?”, the next step is putting “that’s” to work in your own sentences. The short form appears in statements, questions, and short replies.
Everyday Sentences With “That’s”
These sample lines show “that’s” in natural speech and writing. You can read them aloud and then expand each one back to “that is” to check that the meaning still fits.
- “That’s my favorite line in the whole story.” → “That is my favorite line in the whole story.”
- “That’s how this grammar rule works.” → “That is how this grammar rule works.”
- “If that’s true, we need to change our plan.” → “If that is true, we need to change our plan.”
- “That’s exactly what the teacher said.” → “That is exactly what the teacher said.”
- “That’s the point I tried to make.” → “That is the point I tried to make.”
In each case, the contraction keeps the sentence fluent while the full form remains available when you want a slightly stronger or more formal sound.
Questions And Short Replies With “That’s”
“That’s” also fits neatly into questions and brief responses, especially in dialogue.
- Question: “Is that’s the right spelling?” → Better: “Is that the right spelling?” (no contraction after “is” here)
- Statement: “That’s the right spelling.” → “That is the right spelling.”
- Reply: “That’s it.” → “That is it.”
- Reply: “That’s fine with me.” → “That is fine with me.”
The pattern here is simple: use “that’s” to join “that” and “is” when they stand together as part of the sentence, but do not place the contraction right after another verb such as “is,” “was,” or “will.”
“That’s” As “That Has”
One small twist is that “that’s” can also stand for “that has.” One example is “That’s helped a lot,” which expands to “That has helped a lot.” Dictionaries, such as the Cambridge Dictionary definition of “that’s”, list both meanings.
Context shows which meaning fits. In “That’s the correct answer,” the contraction must mean “that is.” In “That’s caused trouble before,” it clearly means “that has.” When you read or write, you can test the line by expanding “that’s” to each full form and seeing which one fits the tense of the rest of the sentence.
Common Mistakes With “That’s” And “That Is”
Because “that’s” is short and handy, writers sometimes drop it into places where it does not belong or mix it up with other forms. Watching for a few common issues will keep your writing tidy.
Mixing Up “That’s” And “Thats”
Many learners type “thats” without an apostrophe, especially on phones and in quick messages. In standard English spelling, plain “thats” does not act as a word. The correct short form is “that’s,” with the apostrophe standing in for the missing letter. If you can replace the word with “that is” or “that has,” you need that apostrophe.
Using “That’s” Where “That” Alone Works Better
Sometimes a sentence feels smoother with just the pronoun “that.” Look at this pair:
- “That’s where the story begins.”
- “That is where the story begins.”
Both sound fine. Now compare these lines:
- “Is that’s your book?” ❌
- “Is that your book?” ✅
In the second pair, “is” already carries the main verb role, so “that” stands alone as a pronoun. Adding “’s” after “that” would double the verb and break the pattern.
Confusing “That’s” With “Its” Or “It’s”
Writers who already juggle pairs such as “its/it’s” or “your/you’re” may feel uneasy about “that’s” as well. The good news is that the pattern stays steady. A contraction such as “that’s” or “it’s” uses an apostrophe because letters are missing, while a possessive form such as “its” carries no apostrophe at all. Resources on standard contractions in English give many side-by-side pairs that show this contrast.
Teaching Learners To Use “That’s” Confidently
Teachers, tutors, and parents often look for simple routines for helping learners master common contractions. “That’s” works well as a model because it appears in clear, concrete sentences and follows the same pattern as other forms built from “is” and “has.”
Step One: Hear And Say The Phrase
Start with short spoken lines. Say “that is” aloud and ask learners to repeat it. Then say “that’s” and repeat. Many students notice that their mouth barely changes position between the two versions. The contraction simply lets the sounds flow together.
Step Two: Write Both Forms Side By Side
On paper or on a board, write two columns. In the first column, list full phrases such as “that is,” “it is,” and “there is.” In the second column, write the matching contractions: “that’s,” “it’s,” and “there’s.” Draw a small marker above the apostrophe in each contracted form so learners see that something is missing there.
Step Three: Expand Contractions In Sentences
Next, give learners sentences that already use “that’s.” Ask them to rewrite each one twice: once with “that is” and once with “that has,” then check which version fits the meaning. This step reinforces the idea that “that’s” has two possible expansions and that context picks the right one.
Table Of Contexts For “That Is” Versus “That’s”
The chart below shows typical situations where either the full form or the contraction feels more natural. These are tendencies, not strict rules, but they help with everyday choices.
| Context | Prefer “That Is” | Prefer “That’s” |
|---|---|---|
| Academic essay | That is because the data show a clear trend. | That’s rarely used in more formal writing. |
| Email to a teacher | That is the topic I chose for my paper. | That’s the topic I chose for my paper. |
| Text message to a friend | That is such a funny clip. | That’s such a funny clip. |
| Instructions or manuals | That is the correct button to press. | That’s the correct button to press. |
| Classroom discussion | That is what the author suggests here. | That’s what the author suggests here. |
| Stories and novels | That is where the trouble began, he thought. | “That’s where the trouble began,” he said. |
| Present perfect tense | That has changed the way we read the data. | That’s changed the way we read the data. |
Quick Checklist For Using “That’s” Correctly
To close, here is a short checklist you can run through whenever you write or edit a line that includes “that’s” or “that is.”
- Can you expand “that’s” to “that is” or “that has” and keep the sentence grammatical? If not, change the form.
- Does the sentence sound too stiff for the audience? Try switching “that is” to “that’s.”
- Is the setting strictly formal, such as an academic paper or exam? Lean toward “that is,” especially in topic sentences and thesis statements.
- Are you tempted to write “thats”? Add the apostrophe and turn it into “that’s.”
- Do you already have a main verb near “that,” as in “Is that your book?” Leave “that” uncontracted in those cases.
Once you have a clear answer to “what is the contraction for that is?”, the pattern behind “that’s” becomes a helpful anchor for learning other contractions. With steady practice, the choice between “that is” and “that’s” soon feels natural in both speech and writing.
