Here's why:
* Linking verbs connect a subject to a noun or adjective that renames or describes the subject. Examples include "is," "are," "was," "were," "seems," "becomes," "feels," "looks," etc.
* "Has" is primarily an auxiliary verb, used to form verb tenses (present perfect, past perfect, future perfect). It can also be a helping verb in other tenses.
Examples:
* Linking verb: "She has been a good student." (Here, "has been" connects "She" to the noun phrase "a good student".)
* Auxiliary verb: "He has finished his homework." (Here, "has" helps to form the present perfect tense of the verb "finish.")
Key takeaway: To determine if "has" is a linking verb, consider the context and whether it's connecting the subject to a renaming or descriptive word.
