Differences between 2 words Thanks and Thank you in English

The selection between "thanks or thank you" may appear straightforward, but this choice plays a crucial role in shaping how others view your level of professionalism and authenticity across both personal relationships and professional environments.

I. Understanding "Thank You"

The Cambridge Dictionary defines "thank you" /ˈθæŋk juː/ as serving dual grammatical roles: as an interjection and as a noun.

• When functioning as an interjection, it conveys appreciation to someone—for instance, "Thank you for coming!"

• In its noun form, it represents the act of expressing gratitude—"A big thank you to everyone who helped." 

The foundational verb "thank" means "to show appreciation to someone," as demonstrated in "I would like to thank Jennie for her generosity."

From a grammatical perspective, saying "thank you" creates a complete sentence structure following the subject-verb-object framework: "I" serves as the understood subject, "thank" acts as the transitive verb, and "you" becomes the object. This construction provides the phrase with enhanced formality and grammatical substance, making it appropriate for respectful or earnest communication. Additionally, it accommodates natural modifiers such as "thank you very much" or "thank you so kindly," maintaining the expression's grammatical completeness and creating a more meaningful and intentional tone.

Common structure: Thank you for (doing) something

Example: Dear Mom, thank you for the lovely dress you sent me for Christmas.

Note: In English, we typically use "Thank you," "Thank you so much," etc., instead of "I thank you" in everyday conversation.

II. Understanding "Thanks"

The Cambridge Dictionary describes "thanks" /θæŋks/ as functioning both as an interjection and as a plural noun.

• As an interjection, it serves to show gratitude—"Thanks a lot for the coffee!"
• As a noun, it represents expressions of appreciation—"My thanks to all of you for your help." 

In contrast to "thank you," the term "thanks" works as a plural noun, operating much like other gratitude expressions such as "appreciation" or "regards." When you give your "thanks," you're essentially providing someone with your gratitude as a concrete offering, which clarifies why we use "thanks for" instead of "thanks to" when showing appreciation for particular actions or gifts. This grammatical difference enables "thanks" to be enhanced with adjectives ("many thanks," "heartfelt thanks") and to function as a sentence subject ("Thanks are in order"), demonstrating its adaptability while maintaining its primary purpose of expressing gratitude.

Common structure: Thanks for (doing) something

Example: Thanks for lending me the money.
