Introduction
Clear writing is one of the most important skills for students, writers, and English learners. Whether you are writing essays, emails, stories, or social media posts, correct grammar helps your message become easy to understand and more professional. Even small spelling differences can change how your writing is perceived. Good writing is not only about grammar rules; it also connects with expression, creativity, and communication. This is where elements like figurative language, descriptive language, and creative writing techniques also support strong expression, making ideas more vivid and engaging for readers.
In English, many learners get confused by small contractions and spelling forms, especially in everyday writing. One common confusion is that’s or thats, which often appears in informal writing, texting, and quick communication. Understanding the difference is important for improving writing skills, vocabulary enhancement, and avoiding common grammatical mistakes.
This article explains everything you need to know about this topic in simple language, including meaning, usage, examples, comparison tables, common errors, and practice exercises to help you master it easily.
1. Understanding “That’s” in English Grammar
“That’s” is a contraction in English. A contraction is a short form of two words joined together by an apostrophe. In this case:
- That’s = That is
- That’s = That has
The meaning depends on the sentence context.
Example:
- That’s my book. (That is my book.)
- That’s been a long day. (That has been a long day.)
Contractions are widely used in spoken English and informal writing because they make sentences shorter and more natural. They also improve fluency in conversation and storytelling.
Understanding contractions helps learners improve writing skills and communicate more effectively in everyday situations.
2. Meaning and Structure of “That’s”
The structure of “that’s” is simple:
- That (pronoun/demonstrative adjective)
- ’s (short form of “is” or “has”)
This creates a flexible expression used in many situations.
Two main meanings:
1. “That is”
Used for description or identification:
- That’s a beautiful painting.
- That’s the reason I came late.
2. “That has”
Used in perfect tense:
- That’s been completed already.
- That’s made me think differently.
This small contraction is very powerful in everyday English because it connects ideas smoothly and naturally.
3. Why “Thats” is Considered Incorrect in Standard English
The word “thats” without an apostrophe is not correct in standard English writing. It is often a spelling mistake made by beginners or fast typists.
Why it is incorrect:
- It does not follow grammar rules of contractions
- It removes the apostrophe that shows missing letters
- It is not accepted in formal writing
However, in informal texting or social media, people sometimes write “thats” casually. Even then, it is still considered incorrect in academic or professional contexts.
Correct form:
- That’s ✔
Incorrect form:
- Thats ✘
Improving awareness of such small details helps learners build strong writing accuracy and avoid common grammar errors.

Avoiding these mistakes improves grammar accuracy and writing clarity.

In spoken English, contractions like “that’s” are extremely common. People naturally shorten words to speak faster and more smoothly.

In written English, usage depends on context:

In formal writing, it is sometimes better to use “that is” instead of “that’s” for clarity and tone consistency.

Tone plays a big role in choosing between contractions and full forms.
Informal tone:
- That’s great news!
- That’s funny!
- That’s cool!

9. Connection with Creative Writing and Figurative Language
Language is not only about grammar rules; it is also about expression and creativity. In creative writing, elements like figurative language, descriptive language, and literary devices make writing more powerful and engaging.
Even a simple contraction like “that’s” can appear in storytelling, dialogue, and poetic expression to create natural speech patterns.
Examples in creative writing:
- “That’s the moment everything changed,” she whispered.
- “That’s how the story begins,” the narrator said.
Use in figurative language:
Writers often combine contractions with:
- Metaphor examples: That’s a storm of emotions.
- Simile examples: That’s like a light in the dark.
- Idiom meaning: That’s the last straw.
These techniques improve storytelling and help writers create emotional depth, imagination, and strong reader connection.
Using correct grammar along with creative techniques improves overall writing skills and vocabulary enhancement.
