Pet vs. Petted – Which is Correct?

The words “pet” and “petted” are both grammatically correct in American English, but they function differently based on verb tense. “Pet” is typically the present tense or infinitive form of the verb, meaning to stroke or caress an animal. “Petted” is the past tense and past participle form of the same verb, indicating an action that has already occurred.

Pet or Petted – Which is Correct?

Both “pet” and “petted” are correct, but they serve distinct grammatical roles related to the verb “to pet.” The core difference lies in the timing of the action. “Pet” is used when referring to the action in the present tense, as a command, or as an infinitive. For instance, “I pet the dog” (present) or “Please pet the cat” (command). “Petted” is used when the action has already happened, functioning as the simple past tense or the past participle. For example, “She petted the puppy yesterday” (past tense) or “The dog was petted by many visitors” (past participle).

The Best Trick to Remember the Difference

To remember the difference, think about the word “acted.” Just as “acted” is the past tense of “act,” “petted” is the past tense of “pet.” If you’re talking about an action happening now or a general instruction, use “pet.” If the action has already been completed, you need the “-ed” ending for the past tense: “petted.”

Word	Part of Speech	Meaning	Example
Pet	Verb (present tense, infinitive)	To stroke or caress an animal gently.	I love to pet my cat when she purrs.
Petted	Verb (past tense, past participle)	Having stroked or caressed an animal gently.	The dog felt happy after being petted.

How to Use Pet

The word “pet” functions most commonly as a verb in its base form, meaning to stroke or caress an animal. It can be used in the present simple tense (“I pet the dog every morning”), as an imperative (“Pet the cat gently”), or as part of an infinitive phrase (“I want to pet the horse”). It conveys an ongoing or habitual action, or a direct request. The tone is generally gentle and affectionate. While “pet” can also be a noun (an animal kept for companionship), in the “pet vs petted” context, the focus is on its verbal usage.

Example 1: Please remember to pet the dog before you leave for work.

Example 2: Every time I visit the farm, I like to pet the goats.

Example 3: She decided to pet the rabbit carefully, as it seemed a bit shy.

What are the different forms of Pet?

As a regular verb, “pet” follows a predictable pattern for its different forms. Note that the consonant ‘t’ doubles before adding ‘-ing’ or ‘-ed’ to maintain the short vowel sound.

• Base Form (Infinitive/Present Simple): pet (e.g., to pet, I pet)
• Present Participle: petting (e.g., I am petting)
• Past Simple: petted (e.g., I petted)
• Past Participle: petted (e.g., I have petted, the dog was petted)
• Third-Person Singular Present: pets (e.g., He pets)

Etymology of the word Pet

The word “pet” has an interesting origin, believed to have emerged in the 16th century. It likely comes from a Scots term, possibly related to “pettie” meaning a small, pampered child, or from the Old French “petit” meaning small. The verb form, “to pet,” developed later in the 17th century, derived from the noun’s meaning of a favorite or indulged animal, implying the act of treating something with affection.

How to Use Petted

“Petted” is the past tense and past participle form of the verb “to pet.” This means it is used to describe an action of stroking or caressing an animal that has already been completed. As a simple past tense, it indicates a specific action in the past (“He petted the cat yesterday”). As a past participle, it can be used in perfect tenses (“She has petted many rescue animals”) or in passive voice constructions (“The stray dog was petted by a kind stranger”). It always refers to an action that is no longer ongoing.

Example 1: The delighted puppy wagged its tail vigorously after being petted.

Example 2: He gently petted the horse’s mane before mounting for the ride.

Example 3: Before she left for vacation, she had already petted all her neighbors’ cats goodbye.

What are the different forms of Petted?

“Petted” itself is a specific form of the verb “to pet.” It serves two primary grammatical functions:

• Simple Past Tense: Used for actions completed at a definite time in the past. (e.g., Yesterday, I petted the kitten.)
• Past Participle: Used with auxiliary verbs (like “have,” “has,” “had,” “be”) to form perfect tenses or passive voice. (e.g., I have petted that dog before. The dog was petted by the child.)

It does not have further forms beyond these two roles, as it is already a derived form of the base verb “pet.”

Etymology of the word Petted

The etymology of “petted” directly follows from the verb “to pet.” As a regular verb, its past tense and past participle forms are created by adding the “-ed” suffix to the base form, with the doubling of the ‘t’ as per English spelling rules for short vowels. Therefore, its historical root is identical to that of “pet,” evolving from the noun meaning a cherished animal to the verb meaning to cherish or stroke.

Related Concepts

Understanding broader grammatical concepts like verb tenses and regular/irregular verbs can greatly help clarify the distinction between words like “pet” and “petted.”

• Verb Tenses: English verbs change form to indicate when an action occurs. The most common tenses are present, past, and future. “Pet” (present) and “petted” (past) are prime examples of how verbs adapt to convey timing.
• Regular vs. Irregular Verbs: Most English verbs are “regular,” forming their past tense and past participle by adding “-ed” (e.g., walk -> walked, pet -> petted). “Irregular” verbs, like “go” -> “went” -> “gone,” have unique forms that must be memorized.

Frequently Asked Questions

Question 1: Can “pet” be used as a noun?
Yes, “pet” can also be a noun, referring to an animal kept for companionship or pleasure (e.g., “My dog is my pet”). However, in the “pet vs petted” comparison, the focus is on their roles as verb forms.

Question 2: Is “petted” ever incorrect?
“Petted” is grammatically correct when used as the past tense or past participle of the verb “to pet.” It would only be incorrect if used in a context requiring the present tense form “pet” (e.g., “I petted the dog every day” should be “I pet the dog every day” for a habitual present action).

Question 3: How do I know whether to double the ‘t’ in “petting” or “petted”?
You double the ‘t’ in “petting” and “petted” because “pet” is a single-syllable verb ending in a consonant-vowel-consonant (CVC) pattern. When adding a suffix that starts with a vowel (like -ing or -ed), the final consonant is doubled to preserve the short vowel sound.

Conclusion

Understanding the distinction between “pet” and “petted” boils down to recognizing their roles as different verb tenses. “Pet” is generally the present tense or infinitive, while “petted” is the past tense and past participle, signifying a completed action. Both are correct and vital parts of the English language, used to convey the timing of the affectionate act of stroking an animal.

Pro Tip: Always consider the timing of the action you’re describing. Using the correct verb tense not only ensures clarity but also reinforces your credibility as a precise communicator, a valuable asset in both professional and personal contexts.
