What is the difference between a modal verb and a linking verb?

Modal verbs express possibility, obligation, or necessity, while linking verbs connect words or phrases in a sentence.

Here's a simple example to illustrate the difference:

• Modal verb: Can you please come?
• Linking verb: We are going to the store.

In the first sentence, "can" is a modal verb that expresses possibility. In the second sentence, "we" is a linking verb that connects the words "we" and "are" in a sentence.

Modal verbs are often used with other modal verbs, linking verbs, or other adverbs. Linking verbs are often used to connect nouns or pronouns.
