What is is?
There are several verbs in English that are not quite ordinary, and their use is not always clear to people who have just started to learn this language. One of these verbs is the verb to be, and is in turn is one of the forms of this verb. So what does is mean? Is is a form of a 3rd person, singular, present tense verb to be. Simply put, we can only use it after the words he (he), she (she), it (it) or words that can be replaced by this pronoun. For example: President, this word can be replaced by the pronoun he, accordingly, after him in the English language will stand is. But the word clouds, we can not replace any of these pronouns, for it is suitable only "they", which is not in this list. Consequently, is after him we can no longer be consumed.
So, the verb to be, and therefore its form is can be used as:
- semantic independent verb, i.e. a verb that carries the meaning of being or existing. For example: He is at home - He is at home. The meaning of the word is is that it is located at home, just translated into Russian, this word is superfluous, and we omit it. Or She is beautiful - She's beautiful (She IS beautiful).The fact is that in Russian the sentence can do without the verb, and in English the verb must be required;
- auxiliary verb, i.e., a verb that helps to form tense forms for other verbs. In such cases, it is not translated at all, but serves as an assistant. For example: She is writing a letter now. - She is writing a letter now. Time is presently continued. Here it is important to remember how this or that time is formed, and is itself will also be in the 3rd person, singular, of the present time;
- modal verb, i.e., a verb that does not denote any action itself, but expresses an attitude towards it. He expresses either the planned action, or orders and orders. And always after is in such sentences there is a particle to. In such cases, is is translated as must, but in different meanings. Consider the examples that we all explain. Marry is to arrive on Friday - Mary should arrive on Friday (planned action). The director says that he must call her because it is his job.
This is what it means ... Of course, it cannot be studied separately, because it is closely related to other forms of the verb to be, which can only be understood together.Only when the grammatical material is learned in the system, it is easy to master.
