Introduction
English can be tricky—especially when punctuation changes the meaning of a word. One of the most common examples of this confusion is that’s vs thats. Many people see both forms used online and assume they mean the same thing. Others aren’t sure whether the apostrophe is optional, informal, or just a stylistic choice.
The confusion usually comes from fast typing, casual writing, and autocorrect habits. Because both versions look almost identical, readers often overlook the small but important difference between them.
Although they look/sound similar, they serve completely different purposes.
In this guide, we’ll clearly explain what that’s and thats mean, how they’re used, where mistakes happen, and how to always choose the correct form with confidence. ✍️
What Is “That’s”?
Meaning and Definition
That’s is a contraction. It is a shortened form of:
- that is
- that has
The apostrophe (’) replaces a missing letter, which is a standard rule in English grammar.
In simple terms:
- That’s = that is / that has
How It’s Used
You use that’s when you want to:
- Speak naturally and conversationally
- Combine words to sound fluent
- Replace that is or that has
It is extremely common in:
- Spoken English
- Informal writing
- Blogs, articles, emails, and conversations
Where It’s Used (Grammar Context)
That’s is correct in:
- American English
- British English
- Formal and informal writing (depending on tone)
Examples in Sentences
- “That’s my favorite movie.” (that is)
- “That’s been a long day.” (that has)
- “I think that’s the right answer.”
Each sentence clearly replaces that is or that has.
Short Usage Note
Contractions like that’s make writing sound more natural and human, which is why they are widely used in modern English.
What Is “Thats”?
Meaning and Definition
Thats (without an apostrophe) is not a correct word in standard English.
In simple terms:
- Thats = grammatically incorrect
It has no meaning, no grammatical role, and no proper usage in formal or informal writing.
Why People Use It
People often write thats because:
- They type quickly
- They forget the apostrophe
- Autocorrect doesn’t catch it
- They assume punctuation doesn’t matter
However, in correct English grammar, thats is always wrong.
Where “Thats” Appears
You might see thats:
- In social media comments
- In text messages
- In unedited content
But its appearance does not make it correct.
Incorrect Examples
❌ “Thats amazing.”
❌ “Thats the problem.”
❌ “Thats what I meant.”
All of these should use that’s instead.
