Thankyou vs. Thank You – Which is Correct?
The correct spelling is always thank you, written as two separate words. The one-word form, thankyou, is a common misspelling and is not considered grammatically correct in standard English. This distinction applies whether you’re expressing gratitude verbally or in writing.
Thankyou or Thank You – Which is Correct?
When expressing gratitude, the correct form in English is always thank you, written as two distinct words. The single-word variant, thankyou, is a widespread misspelling. This error often arises from phonetic confusion, as the phrase is spoken quickly and sounds like a single unit, leading people to incorrectly merge the words in writing. However, “thank” functions as a verb and “you” as a pronoun, requiring them to remain separate.
The Best Trick to Remember the Difference
To easily remember that “thank you” is two words, think of other common verb-pronoun combinations. You wouldn’t write “loveyou” or “seeyou”; you write “love you” and “see you.” The same logic applies to “thank you.” If you can insert an adjective between “thank” and “you” (e.g., “thank you very much“), it confirms they are separate words.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| thank you | Interjection / Verb Phrase | An expression of gratitude or politeness. | “Thank you for your help.” |
| thankyou | Incorrect | A common misspelling of “thank you.” | Incorrect: “Thankyou for the gift.” |
How to Use Thank You
“Thank you” is a versatile expression used to convey gratitude. It functions primarily as an interjection, a standalone expression, or as a verb phrase where “thank” is the verb and “you” is the direct object. It is universally polite and can be used in both formal and informal contexts.
Example 1: “Thank you for coming to my party; it means a lot to me.”
Example 2: “Please accept this small token of appreciation. Thank you for your unwavering support.”
Example 3: “When the waiter brought the check, she simply said, ‘Thank you,’ with a smile.”
Etymology of the word Thank You
The phrase “thank you” is a direct and literal expression derived from the Old English word “þancian,” meaning “to thank, give thanks, or reward.” This verb is related to “þanc” (thank, thought, gratitude). Over time, the verb “thank” combined with the second-person pronoun “you” to form the common expression of gratitude we use today. The separation of the words reflects their distinct grammatical roles, with “thank” acting as the verb and “you” as its object.

- Verb-Pronoun Phrases: Many English expressions consist of a verb followed by a pronoun acting as its object. Examples include “see you,” “miss you,” and “love you,” all of which maintain their two-word structure.

Frequently Asked Questions
Question 1: Is “thank you” always two words?
Yes, when used as an expression of gratitude, “thank you” is always written as two separate words. The verb “thank” and the pronoun “you” maintain their individual identities.
Question 2: What about “thank-you” with a hyphen?
While “thank you” as an expression of gratitude is two words, the hyphenated form “thank-you” is used when it functions as an adjective modifying a noun (e.g., “a thank-you note,” “a thank-you gift”) or as a noun itself (e.g., “she received many thank-yous“). Without the hyphen, “thank you note” is also acceptable, though “thank-you note” is often preferred for clarity when used attributively.
Question 3: Can “thankyou” ever be correct?
No, thankyou as a single word is never considered correct in standard English for expressing gratitude. It is a common misspelling. Always use “thank you” (two words) or “thank-you” (hyphenated as an adjective or noun, as explained above).
Conclusion
The distinction between “thankyou” and “thank you” is clear: “thank you” is the only correct form for expressing gratitude. While the one-word misspelling is common due to how the phrase sounds, maintaining the two-word separation is essential for grammatical accuracy. Remember that “thank” is a verb and “you” is a pronoun, and they function independently within the phrase.
Pro Tip: Always proofread your written communications, especially in professional contexts. Correct spelling and grammar, including the proper use of “thank you,” reinforce your credibility and attention to detail.
