At which linguistic stage do children begin using simple sentences?

Children typically begin using simple sentences around the age of 3 years. At this stage, their vocabulary has expanded significantly, enabling them to string together two or more words to express their thoughts. This marks a critical transition from single-word utterances to more complex forms of communication.

By the age of 3, many children can form simple sentence structures, such as “Mommy go” or “More juice,” demonstrating their ability to convey a basic idea or request. This linguistic advancement is an essential part of their cognitive and social development, as it allows them to engage more effectively with their caregivers and peers. This stage of language development lays the foundation for more complex sentence structures that emerge in later years.
