Is this a correct sentence using a linking verb? My dog Sam is in the bathtub. Is "is" the linking verb?

Please note the correct spelling -- grammar!!

Yes, "is" is the linking verb. There is no predicate noun, but the prepositional phrase after "is" is telling where the dog is.

Please note the spelling of GRAMMAR.

Yes, you've used the linking verb "is" correctly.

Yes, the sentence "My dog Sam is in the bathtub" is correct and it does contain a linking verb.

To identify a linking verb, it's important to understand what a linking verb does. A linking verb connects the subject of a sentence to a noun, pronoun, or adjective that describes or renames the subject. It doesn't show action, but instead, it links the subject to additional information about it.

In this sentence, the linking verb is "is," which connects the subject "My dog Sam" to the phrase "in the bathtub." The verb "is" helps to describe the location of the subject.

To determine if "is" is indeed a linking verb, you can test it by substituting it with other linking verbs like "am," "are," "was," etc. In this case, you can replace "is" with "isn't," which is a contraction of "is not," and the sentence still makes sense: "My dog Sam isn't in the bathtub." This confirms that "is" in the original sentence is a linking verb.
