When do children typically start using future tense in their expressive language?

Children typically begin to use future tense in their expressive language around the age of 5 years. At this stage in development, children are refining their language skills and expanding their understanding of time-related concepts. They become more capable of expressing ideas about what will happen in the future, using words like "will" or "going to" to indicate future events.

This milestone demonstrates their growing cognitive abilities, particularly in understanding the concept of time, as well as their improved sentence structure and vocabulary. By age 5, many children can construct simple sentences using future tense, which is a key component of effective communication as they continue to develop their language skills.
