What vocabulary size is common for a 3-4 year old child?

A vocabulary size of around 1,000 words is common for a 3 to 4-year-old child. At this developmental stage, children are rapidly expanding their language skills as they engage more with their environment and those around them. They are beginning to use more complex sentences and are able to follow conversations, express their thoughts, and describe their experiences more vividly. This vocabulary growth is largely influenced by factors such as interaction with caregivers, exposure to language-rich environments, and their own innate curiosity. Various studies in language development support this range, highlighting that 1,000 words is a healthy estimate for children at this age, enabling them to communicate effectively in daily situations.
