What does knowing a larger number of words contribute to?

Knowing a larger number of words significantly enhances the ability to communicate ideas clearly. This vocabulary expansion allows individuals to express their thoughts, feelings, and concepts more precisely, facilitating effective communication. When learners have access to a rich vocabulary, they can articulate their messages in a way that is easily understood by others, which is crucial in both spoken and written forms.

Moreover, a robust vocabulary directly influences reading comprehension; as individuals encounter more complex texts, their ability to understand and analyze these materials greatly improves. This clarity in communication is essential not only in educational settings but also in social interactions and professional environments, leading to more meaningful exchanges and collaborations. Thus, vocabulary knowledge plays a pivotal role in enhancing communication skills, making it the most fitting answer in this context.
