Most children can typically speak in full sentences and possess a good vocabulary by the age of 5. At this stage of development, children usually have a fundamental understanding of sentence structure and can express their thoughts more clearly. They often have a vocabulary that allows them to engage in simple conversations and describe their experiences in a coherent manner.

While some children may continue to refine their language skills and vocabulary beyond this age, the foundation for effective communication is largely established by 5 years old, making this the developmental milestone for speaking in full sentences and using a substantial vocabulary. Therefore, suggesting an age older than 5 for this skill does not align with the typical developmental norms for language acquisition in early childhood.
