Answer:"Immediately" is not a modal verb. It's an adverb that describes the timing of an action. It indicates that something happens without delay, right away. Modal verbs are helping verbs that express things like possibility, necessity, obligation, or permission. Some examples of modal verbs include: - Can, could (ability, possibility)- May, might (possibility)- Must, should, ought to (obligation)- Will, would (future tense, willingness)- Shall (future tense, determination)
