Let's think about the importance of language in our life. We need language when talking to others, listening to other people, reading, writing and thinking. Thanks to the language we acquire from birth to adulthood, we can describe past events, think about the future and make plans.  Therefore, we unconsciously need language for many actions we perform in our daily lives.

​

   All languages created by humanity have common characteristics (Berko Gleason, 2009). At the beginning of these characteristics are endless productivity and organizeable rules. In other words, each language can express endless thought within itself, by using certain rules of productivity.  provides.

   Since it was thought that language was learned in the same way as walking, running and swimming in ancient times, it was tried to be explained by taking into account the basic learning principles, but when this situation could not explain many things, it was concluded that language development was a more special development process in itself and occurred with certain milestones.  These milestones are considered as trying to make sense of language sounds (recognizing language sounds), making various vocalizations (babbling, crying, cooing), trying to express oneself with gestures and signs (gestures), using the first words and trying to explain oneself with two or three words.
