First of all, we must understand some points.
There are two ways of classifying verbs.
According to the it’s priorty, a helping or auxiliary verb and the main verb.
According to the person doing the verb or action, known as conjugation.
A main verb is a verb that is considered the real thing or action done in the sentence.
An auxiliary verb, on the other hand, is a verb that is used to defferenciate between the main verb alone and the main verb along the helping verb, where a helping verb is used with the main verb to make a new slightly different tense.
You have to know that there are only two verbs that can work as auxiliary verbs. These are verb to be and verb to have. Although they are considered the only auxiliary verbs, they can also be used as main verbs.
There are three main types of tenses in English, past, present and future.
The ordinary version of these tenses is called simple and it consists only of the main verb. Other versions are called continuous and participial; these are other forms of tenses. They consist of an auxiliary verb and a main verb.
For now, we are going to study present only, let’s have an example “, I go to school every day” is in simple present tense and it means that you go to school repeatedly in the present.
Thus, simple present tense discribes an action that happens with a rate in present. It consists only of verb to be.
Most of the time, simple present will be used when a situation or an action is always true or a fact, unless a keyword that shows rather than that is used.
But, if I say “I am going to school now,” this is continuous present and it means that I am going to school at the current time; It does not necessararily mean that I am go to school every day. In other words, I am going to school right now, not tomorrow.
Therefore, continuous present is used to discribe an action that is happening only at the current time, not happening repeatedly. It consists of verb to be as an auxiliary verb and the main verb with ing added to it’s end.
Continuous present can also be used to discribe what is happening in an image or an action that is developing or changing in present. For example “, Prices are continuously rising”.
In continuous present, verb to be is considered a helping verb because it does not represent the main action. The main verb represents the main action. Simple present only consists of the main verb.
We are going to explain how verbs are conjugated in present, but before that, we have to understand something.
There are six types of persons in English. First person singular (I), second person singular (you), third person singular (he, she, it), first person plural (we), second person plural (you) and third person plural (they). Each one of these has it’s own conjugation.
To make it simple, we are going to arrange them in groups, group one which contains the first person singular (I) and plural (we), the second person singular and plural (you), third person plural (they). Group two only contains the third person singular (he, she and it).
In present, the verb can take two shapes according to the person that do(es) it.
First shape is the infinitive one or the basic one, where the verb is in it’s basic form.
This is used with group one of persons. So, using the verb go with these pronouns won’t make any change in the verb. “I go to school” “, We go to school every day,” “You go to school every day” or “They go to school every day”.
Second shape is the shape when the doer is one from the second group of persons. In this shape, the verb takes an “actual” conjugated form.
The general rule is adding s to the end of the verb. If the verb ends with s, sh, ch, o or x, we add es to it’s end. If the verb ends y, then change the y to i and add es.
That said, now we can understand the defference between has, have and had.
Have is the base verb; the conjugated version that works with group one of persons. Has is the verb conjugated in present for group two of persons. Had is the past version of the verb. Had is used for both first and second group of persons in the past tense.
Have can be used both as a main verb and an auxiliary verb. It can be used as an auxiliary verb in past participial tense. Where it consists of have as a helping verb and the main verb in past participial conjugation. And, do not forget that it can also be used as a main verb; where it means to own or possess.
