which form of verb tense is the underline phrase(you should have invited them to the party

The underlined phrase "have invited" is in the present perfect tense.

To identify the verb tense of a sentence, you can follow these steps:

1. Identify the verb: In this sentence, the verb is "invite."

2. Determine the auxiliary verb: Look for auxiliary verbs (also known as helping verbs) that are used along with the main verb to indicate the tense. In this case, "have" is the auxiliary verb.

3. Consider the form of the main verb: The main verb "invite" is in the past participle form, which is "invited."

4. Analyze the auxiliary verb and the past participle: When the auxiliary verb "have" is combined with the past participle "invited," it forms the present perfect tense.

In the sentence, "should" is also an auxiliary verb, but it is expressing a modal verb (indicating advice or obligation) rather than the verb tense.
