What a person says is the embodiment of his thoughts and feelings, and therefore of himself. Of course, in speech, he does not express all his secret thoughts. And yet, the way a person speaks and what he starts talking about can tell a lot about him.
With the help of speech, a person can express his thoughts, convey to the interlocutor what he is feeling at the moment, what his thoughts are doing, what his experiences are. The manner of a person's speech can show what he really is, what his mind is busy with, what he lives with, what affects his life, what is his range of interests and what is the level of education. A person's statements can be analyzed quite simply, answering the question of who the person really is, what he wants and how he lives.
It is not for nothing that the language of each new generation changes. If you compare the speech of a representative of the 19th century with a person from the 20th century, you can see a significant difference not only in judgments, but also in words, expressions, and the composition of sentences. What was previously important for people gradually disappeared from their lives and, accordingly, speech. Words such as "sir", "charioteer", "coachman", so often encountered in the speech of representatives of the 19th century, fell out of use. They were replaced by new words, because new objects and phenomena appeared, which they denoted. The words "comrade", "driver", "taxi driver" were borrowed from other languages or transformed from older words into new forms. And in the 21st century, they were replaced by new expressions again, filling the familiar meaning with new word forms. Thus, a person's speech is constantly changing, filled with new words and gets rid of old ones.
Historical, political events taking place in the country are of great importance for changing speech. The speech of an individual person is influenced not only by global processes, but also by his level of education and curiosity. The speech of a child and an adult is strikingly different from each other. Children's vocabulary is replenished from the environment of the child - parents, educators or teachers, friends. An adult's speech is based not only on his environment, but also on education and vast experience of communication. An adult can vary linguistic forms, change them depending on the situation. So, he is affectionate and gentle in a family environment and serious in the business sphere. Therefore, his speech changes along with his mood and circumstances, is an expression of his true "I", his position in relation to the people around him.
A person may not express all his thoughts in words, but speech is not only a collection of words and expressions. Speech is also intonation, meaning not only what a person said, but also how he said it. And this is also a reflection of a person's attitude to other people, objects or events. Therefore, at every moment of a speech utterance, a person shows himself, talks about himself and his attitude to what is happening, because speech is himself.
