In what stage do children typically start using two-word sentences?

Children typically start using two-word sentences during the two-word stage of language development. This stage generally occurs around 18 to 24 months of age, when children begin to combine two words to form simple sentences that convey more complex ideas than single words alone. For example, a child might say "want cookie" to express a desire rather than just using a single word like "cookie."

In this stage, the combinations of words often reflect key aspects of their environment and experiences, allowing children to convey meanings such as possession, action, or simple requests. The two-word combinations are characterized by their simplicity and directness, and although they may not adhere to grammatical rules, they show a significant advancement in a child's ability to communicate effectively.

This stage marks an important transition in language development, paving the way for more complex sentence structures that children will develop in subsequent stages.
