As children learn the words not only for conversation but also to use it in the right context. Choosing the words rightly and framing it in the right way is how it works. Some children know how to use it but some face some challenges in framing and the correct context to use it. They might discuss some unrelated words and phrases where they are not supposed to.

The struggle can be lightened from the home with proper guidance and support. If that doesn't work, a proper professional consultation will help them to develop their language.
