The modal verb “will” is used in all aspects of the future tense (e.g., “I will talk,” “you will be traveling”). When a modal verb is followed by another auxiliary verb (e.g., “have,” “be”), the main verb takes either the past participle form (typically ending in “-ed,” “-n,” or “-t”) or the present participle form (ending in “-ing”). Modal verbs can be used along with auxiliary verbs to refer to possible past, continuous, or future action. Examples: Auxiliary verbs in a sentenceMary was building a sandcastle.
