At what age do children typically start to form simple sentences?

Children typically start to form simple sentences around 2 years of age as they reach a significant milestone in language development known as the two-word stage. During this period, toddlers begin to combine words to express simple ideas, such as "want cookie" or "more juice." This ability indicates that they are not only understanding individual words but are also beginning to grasp the structure of language, allowing them to communicate their needs and thoughts more effectively.

At this age, their vocabulary is expanding rapidly, and they begin to experiment with sentence formation, often omitting less critical words in their utterances, which is characteristic of this developmental stage. This marks a foundational step in their language acquisition, setting the stage for more complex sentence structures and richer language use as they grow older.
