Which stage typically sees the use of complex sentences containing three or more words?

The complex sentence stage is characterized by the ability to use grammatically correct complex sentences that include multiple clauses and a variety of vocabulary. At this stage, children demonstrate advanced language skills, reflecting their growing understanding of syntax and sentence structure. Typically occurring around age three to five, children begin to combine ideas and express more complex thoughts, incorporating conjunctions and other elements that allow for longer and more detailed expressions.

This stage represents a significant developmental milestone, indicating that children are not only expanding their vocabulary but also mastering the nuances of language that enable them to communicate effectively and convey more sophisticated meanings. In contrast, the one-word, babbling, and two-word stages involve much simpler expressions, limited primarily to either single words or basic combinations that do not reach the complexity of the sentences formed in the complex sentence stage.
