99+Thankyou or Thank You: What’s the Right Form? 2025

🧐 What Does Each Word Mean?

Let’s look at both forms one by one.

✅ “Thank You” – The Correct Form

• Part of speech: phrase (a combination of a verb and a pronoun)
• Meaning: used to show gratitude or appreciation to someone.
• Structure: “thank” (verb) + “you” (pronoun)

Examples:

1. Thank you for helping me with my homework.
2. I just wanted to say thank you for your kindness.
3. Thank you for inviting me to your party!

Think of it this way: when you’re saying thank you, you’re thanking a person directly. The two words need space to work together.

❌ “Thankyou” – The Incorrect Form

• Part of speech: ❌ not a real English word (misspelling)
• Meaning: none — it’s a spelling mistake of “thank you.”

However, you might see it written as one word in casual online posts, creative logos, or brand names.
For example, a company might name itself “Thankyou™” (like the Australian social enterprise brand).

Examples (incorrect in normal writing):

1. I want to thankyou for your help. ❌
2. Thankyou so much for coming! ❌

Remember: unless it’s part of a brand name, always write thank you as two words.

🚫 Common Mistakes and How to Avoid Them

❌ Mistake 1: Writing “thankyou” in emails

Incorrect: Thankyou for your quick reply.
Correct: Thank you for your quick reply.

👉 Why it’s wrong: “Thankyou” isn’t a recognized word in English grammar.

---

❌ Mistake 2: Using “thankyou” in formal writing

Incorrect: We would like to express our sincere thankyou to our team.
Correct: We would like to express our sincere thanks to our team.

👉 Why it’s wrong: In this case, you need a noun form (“thanks”), not the phrase “thank you.”

---

❌ Mistake 3: Confusing “thank you” (phrase) with “thank-you” (adjective)

Correct: She gave me a thank-you card.
👉 When used as an adjective before a noun, you can add a hyphen (thank-you).

So, we have three forms:

• thank you → phrase (used in sentences)
• thank-you → adjective (before a noun)
• thanks → noun (general gratitude)

✨ When to Use “Thank You”

Use thank you whenever you are directly expressing gratitude to someone.

Examples:

1. Thank you for waiting patiently.
2. Thank you for your message — I appreciate it.
3. Thank you for helping me clean the room.
4. Thank you so much for your advice!
5. Thank you for reading this article. 😊

💭 Memory Hack:
Imagine giving someone a gift — you need two hands (just like the two words, “thank” and “you”) to show kindness properly!

🌼 When to Use “Thankyou”

Normally, you don’t use “thankyou” in writing or speech.
The only time it’s acceptable is when it’s part of a name, logo, or brand, such as:

• “Thankyou™” water (a real company name)
• “Thankyou App” (a brand name in creative writing)

Outside of these cases, always write thank you separately.
