What does the term 'expressive language' refer to?

The term 'expressive language' refers to the ability to articulate and communicate thoughts, feelings, and ideas effectively through spoken or written language. This encompasses a range of skills, including vocabulary use, sentence structure, and the ability to convey meaning clearly to an audience. Expressive language is crucial for effective communication, allowing individuals to share their perspectives and engage in dialogues.

In contrast, other options focus on different aspects of language skills. Reading fluently pertains to how smoothly a person can read aloud, while understanding complex texts relates more to comprehension skills. Decoding, on the other hand, specifically involves recognizing and pronouncing words, which is more about the technical aspect of reading rather than expressing one's own ideas. Therefore, the correct choice highlights the key function of expressive language in communication.
