Lexical development of the child until the school starts pretty early. The child in its earliest days, shortly after birth, begins with the adoption of language elements. From crying and releasing votes, to releasing unarticulated sounds, adopting the first words, creating innovative semanthems all the way to the ability to assemble their own sentences - it is all part of a process called language adoption. Working with a child contributes to his or her desire to learn. Parents, educators and teachers must be creative in their efforts to teach a child something. In addition, they must be aware that language adoption is a complex and demanding process. Not all children are the same, as not all adults are the same. Let the children more quickly overcome the obstacles they encounter when they learn the language, while there will be children who will struggle hard on that path. This problem is of individual nature and can hardly be influenced by it. If the child has any problems that interfere with language learning, it is extremely important to react in time and work to resolve the problem. Only in this way will the child be removed from the possibility not to overcome a language element. From everything written in the paper, it should be said that language developmental speech picks a person throughout his life. From the earliest days when a child adopts the first votes until the last day until when we have the opportunity to learn something new related to his or her native language.
