 When we talk about language, then language, you know, child just develops after the birth and when it comes to the environment, then there are many sources of learning language. There are many factors to learn a language. It can be a mother language. It can be another language. It can be a second language. So these are the different types of languages that we learn through our throughout our life. Here is the referential language. Now, since the development of language is taking place since childhood, the referential means that the first thing that the child expresses in the language that they learn is a word papa, mama, or they will make a sign of water, or they will take some help from the broken words. So the reference is that if you want to drink water, then you will put your hand on the glass, or they will give a reference of something, they will tell you, they will smile, or they communicate with you. So the first stage of the referential language is that the child learns one word, then he joins two words, then he makes a sentence to communicate to you. So this is the start of the language learning. It is a style of right time learning of language in which children use language for the most part to label objects. Now they are learning, this is cup, this is bottle, this is glass, this is toy, this is train. Now their vocabulary is increasing. So referential means that they know the pictures of the objects and they can understand and identify these items by even only seeing the pictures that the dog, cat, when they see their pictures, they can easily recognize them in the street, that this is dog, this is cat, then we are showing them videos, they are watching cartoons. They also get to know a lot about objects. Even if they haven't read the rules or the book yet, but after seeing the pictorial language, they can reference, they can quote. And this is a referential language of learning. In which they are learning things with the reference of objects. And in each language, an object has a different name. So if a child is learning two or three languages, such as mother tongue, its national language, its second language, so now he knows how to express this word in three languages. So basically the children are learning different words of an object. They also know the differences. So here this style is useful to young children because this way extends their understanding of vocabulary. So you know at this childhood stage they know that the bear and bear, this is the one word, but it has two different meanings. So now the reference means that they should be shown two pictures. Look at this, this is the name of an animal and this is the tolerate which we say we do. This is what it means. So the references we are giving to the children with that reference, we are explaining to them about any vocabulary or any word. So the intelligence and their mental state, they can learn easily. They can learn these two types of meaning, different meaning, double meaning. And with the reference of the objects, they can learn and they can correlate the meaning and the word with the objects. First they learn that this is a cat, then they learn that this is a dog. Dog and cat are two different animals. A dog can bite you, a cat can be more friendly with you. This means that they start learning that this is a dog, but a dog is dangerous. But the cat is not dangerous. This is a new concept with which they understand the meaning of the reference. Along with that, the whole story starts to connect with the word, the sentence and the meaning of it and understand it. So this is a reference that now they are not able to express any concept without reference or referral or picture or any other object. Now you can tell them what is critical thinking. It is a thought that they have to explain it abstractly. So this thing is not being explained yet because this is the beginning stage of the language in which they bring the reference and objects into their mind and tell you the whole story. Now they are dangerous, they are good, bad and horrible. All these things are objects like black or dark. They will understand that this is dangerous. Because you have told them that darkness is dangerous and their fear is there. So all these dark things will feel like this. You will say that I was very scared. Seeing that, its color was black. This is a sign of fear. That is why I am telling you the reference. Because of this, I was scared because its face was like this. So when we ask the child why he is happy today, he will give a reference that he is my favorite dish. He made it today but you have spoiled its shape. He has learned to explain with reference that its taste is not good, I don't want to eat it. Its taste is good because its presentation is very good. Its face is very good because of which I eat it. Now the child learns and can be able to give reasons of doing anything or of eating anything or of taking any action. So it means that the span of its language has increased from one word sentence to a little paragraph. Now instead of one thing's reference, it can be related to two or three things with reference. What are the good things? It will make you in a group. What are the good things? It will make you in a group. If a human being doesn't like it, it will mix it with an animal's reference. If someone likes it, it will call it fairy, or it will call it prince, or it will call it princess. Now with references it can express any personality or it can explain it in this stage. So this is the stage of the reference, your referential language development that child is learning.
