In language acquisition, which type of vocabulary is essential for expressing thoughts verbally?

The option identified as correct highlights the type of vocabulary that directly supports verbal expression. Speaking vocabulary refers to the words an individual actively uses when they communicate orally. This vocabulary is crucial for articulating thoughts, engaging in conversations, and effectively conveying ideas to others.

Having a robust speaking vocabulary enables individuals to express themselves clearly and confidently in spoken language. While other forms of vocabulary, such as written, listening, and reading, contribute to overall language comprehension and communication, it is the speaking vocabulary that specifically facilitates verbal expression.

In contrast, written vocabulary encompasses the words one can use in writing, listening vocabulary involves words one understands when listening to others, and reading vocabulary pertains to the words one can decode and comprehend in written texts. While these are all important components of language skills, they do not directly facilitate verbal communication in the same way that speaking vocabulary does.
