At what age do most children begin to speak in simple two-word sentences?

Most children typically begin to speak in simple two-word sentences around 24 months of age. This milestone marks an important stage in language development, commonly referred to as the "two-word stage" of speech. At this age, children start to combine words to express more complex ideas and needs, moving beyond single words. For example, they may say phrases like "want cookie" or "more juice," indicating not just the request but also developing grammatical understanding.

This period in language development is influenced by cognitive advancements, social interactions, and exposure to language. By 24 months, children often have a vocabulary of around 50 words, allowing them to begin forming basic sentences that convey their thoughts and desires more clearly. It is a significant leap towards more advanced language skills that will develop as they grow older.
