Thank Someone vs. Thanks Someone – Which is Correct?

“Thank someone” and “thanks someone” are both correct, but they serve different grammatical roles. “Thank” is the base verb used with I, you, we, they, commands, and infinitives. “Thanks” is the third-person singular present-tense verb or a noun/interjection. Choose the form that agrees with the subject and sentence structure properly.

Thank Someone or Thanks Someone – Which is Correct?

“Thank someone” and “thanks someone” are both correct expressions. The correct choice depends on the grammatical subject and the role of the word in the sentence.

Thank is the base form of the verb. Use it after subjects such as I, you, we, and they, after modal verbs, in infinitives, and in commands. For example, “I thank my mentor,” “They thank the volunteers,” and “Remember to thank your host.”

Thanks is usually either the third-person singular form of the verb or a noun expressing gratitude. Use it as a verb with a singular subject such as he, she, or the manager: “She thanks her team.” As a noun or interjection, “thanks” appears in expressions such as “Thanks for your help.”

The Best Trick to Remember the Difference

Use the he, she, it test. If the subject is he, she, or it, use the verb thanks: “She thanks her colleague.” With I, you, we, or they, use thank: “They thank their colleague.”

When “thanks” means gratitude rather than an action performed by a subject, it can stand alone or follow a preposition: “Thanks!” and “Many thanks for responding.”

How to Use Thank

Thank is the base form of the verb meaning “to express gratitude to someone.” It normally takes a direct object: “thank someone.” You can also thank someone for something or thank someone by describing the reason for your gratitude. The word works in formal and casual communication, although phrases such as “I thank you” can sound more formal than the conversational “Thank you.”

Use thank after plural subjects and the pronouns I, you, we, and they. It also follows modal verbs such as can, should, and will, as well as the infinitive marker to.

Example 1: We thank everyone who contributed to the community project.

Example 2: Please thank your parents for their generous support.

Example 3: I want to thank you for explaining the process so clearly.

Etymology of the word thank

Thank comes from the Old English word þancian, meaning “to give thanks” or “to express gratitude.” It is related to þanc, meaning “thought,” “goodwill,” or “gratitude.” The connection reflects the older idea that thanking someone involves recognizing or acknowledging a good deed.

How to Use Thanks

Thanks has two common grammatical functions. First, it is the third-person singular present-tense form of the verb thank. In this use, it must have a singular subject: “The customer thanks the representative,” or “She thanks him for his assistance.”

Second, thanks is a noun or interjection expressing gratitude. It can stand alone in casual conversation—“Thanks!”—or appear in phrases such as “many thanks,” “thanks for your message,” and “thanks to your advice.” As a noun, it is often less formal and more concise than “thank you,” though “many thanks” can also sound polished in emails and letters.

Example 1: She thanks her colleagues for helping with the presentation.

Example 2: Thanks for sending the updated document.

Example 3: Many thanks for your prompt response.

What are the different forms of thanks?

When thanks is a verb, it is the third-person singular present form of thank. The other verb forms come from the base word thank: thanked and thanking. When thanks is a noun, it is usually treated as a plural-form expression referring to words or expressions of gratitude.

• Verb: thanks — “The director thanks the cast.”
• Noun or interjection: thanks — “Thanks for the invitation.”
• Common expressions: “Many thanks,” “Thanks a lot,” and “Thanks to your help.”

Etymology of the word thanks

Thanks developed from the plural noun form of thank, which traces back to Old English þanc, meaning “thought,” “gratitude,” or “acknowledgment.” The verbal form thanks developed through the regular English pattern of adding -s to a present-tense verb used with a singular third-person subject.
