The topic of the given research is connected with the investigation of there sentences in English The word there is a polysemeous word and can be a pronoun or an adverb. As a pronoun it can be used as the subject of the verb 'be' to say that something exists or does not exist, or to draw attention to it; in front of certain verbs when you are saying that something exists, develops, or can be seen. Whether the verb is singular or plural depends on the noun which follows the verb; The word there can be used in the form of convention. It is used after 'hello' or 'hi' when you are greeting someone. When the word there is used as an adverb its semantics varies. The question of how the two ways of using there originated also plays some part in synchronic treatments, as reflected in recent developments in linguistics. In the field of generative grammar, defining the categorial status and syntactic function of there is of central importance. Grammarians are unanimous in their view that the there is often a subject in a sentence. However, there is disagreement about whether there is introduced transformationally, or whether it is already present in the syntactic deep structure. Proponents of generative grammar separate nominal there very strictly from adverbial there. They tend to regard the identity of form as coincidental. Syntactic analyses contribute little or nothing about the semantics of there. Characteristic of this is the recurrent description of there as "dummy there", indicating that it has no meaning. But we should say that in spite of the fact that dummy words have no meaning they do have a grammatical function. The author investigates syntax and semantics of the word 'there'. In the article the ambiguity of sentences with the word 'there' and its emphatic characteristics are shown.
