Explanation
A verb is the part of speech that expresses an action.
The verb is the heart of a sentence - every sentence must have a verb. Recognizing the verb is often the most important step in understanding the meaning of a sentence.
A verb is the essential part of the predicate of a sentence.
The grammatical forms of verbs include number, person, and tense.
 
There are two main categories of verbs:
1. Action verbs (main verbs, that is, verbs that aren't dependent on other verbs)
2. Auxiliary verbs (also called helping verbs). The two subtypes of auxiliaries are:
    a. the primary auxiliaries (be, have, and do), which can also act as action verbs
        I am writing. (auxiliary verb)                          
        I am a teacher. (action verb)
    b. modal auxiliaries (can, could, may, might, must, etc.)
        I can write.
 
Verbs that form the simple past tense by adding -d or -ed are called regular verbs.
Irregular verbs contrast with regular, that is, they don't have -d or -ed ending in the past tense. 
You must memorize them.
  
One of the most important things about verbs is their relationship to time.  Verbs tell us if the action is a fact or a habit (simple present, past, or future); if it is happening at he moment of speaking (progressive or continuous present, past, future), etc. See the chart below. More verb tenses will be discussed later, in other lessons.

Watch out
Simple present tense verbs have a special form for the third person singular, they take the ending -s (works).
Singular means one and plural means more than one.
Person is used here to show who or what does the action and can have the following forms:
    1st person singular (I)                      1st person plural (we)
    2nd person singular (you)                2nd person plural (you)
    3rd person singular (he, she. it)       3rd person plural (they)
The third person singular forms are represented by the pronouns he, she, it. 
The chart below shows how the third person singular verb forms change:

The future simple is usually used in promises.
I promise I will not tell him about the surprise party.
I won't tell anyone your secret.
The future simple is used to make predictions that are based on personal judgement, opinion or intuition. Whether or not the event will happen is not certain. Such predictions are often introduced by
I think / I don't think / I hope, etc.
I don't think he'll come tonight.
