Hint: A verb is a word or a group of words that describes an event, a state of being, or a situation. The part of a sentence that tells us what the subject does is called a verb.

Complete answer:
A verb (part of speech) is a word (part of speech) that conveys an event (bring, read, walk, run, learn), an occurrence (happen, become), or a state of being (happen, become) (be, exist, stand). The infinitive is the simplest type of English, and it can be used with or without the particle to. Verbs are inflected (changed in form) in many languages to encode tense, aspect, mood, and expression. Any of its arguments, such as the subject or object, may also agree with the person, gender, or number of the verb's arguments. The present tense indicates that an action is being carried out; the past tense indicates that an action has been completed; and the future tense indicates that an action will be completed.

There are three tenses for verbs: past, current, and future. Things that have already occurred are described in the past (e.g., earlier in the day, yesterday, last week, three years ago). The present tense is used to describe events that are currently taking place or that are ongoing. Things that haven't happened yet are defined in the future tense (e.g., later, tomorrow, next week, next year).

In the sentence given above, the term 'next month' indicates that it will happen in the future. As a result, the future tense should be used. So, we will use ‘will be leaving’ in the above sentence.
Correct sentence: Sunder will be leaving for America next month. This sentence shows that Sunder will be in the midst of his journey to America next month.

Note: Verbs come in a variety of types, each of which is defined by the words that surround it and their relationship to the verb. Intransitives, transitives, ditransitives, and double transitive verbs are commonly divided into three categories based on the number of valency arguments they have.
