Vocabulary growth refers to the process of expanding the number of words a person knows and uses. This growth can occur through various means, such as reading books, engaging in conversations, and studying new languages. A rich vocabulary enhances communication skills and comprehension, allowing individuals to express themselves more clearly and understand others better. Factors influencing vocabulary growth include age, education, and exposure to diverse language environments. Children often experience rapid vocabulary growth as they learn to speak and read, while adults can continue to expand their vocabulary through lifelong learning. Tools like dictionaries and thesauruses can also aid in this development.
