Which of the following could be a sign of an expressive language disorder?

In the context of expressive language disorders, the ability to articulate thoughts clearly is a key component that can often be impaired. Expressive language involves the ability to convey thoughts, ideas, and feelings through speech and language. When someone has an expressive language disorder, they might struggle to organize their thoughts, find the right words, or form coherent sentences, which can make their communication seem unclear or fragmented.

In contrast, making eye contact while speaking, following directions properly, and using a wide variety of vocabulary are generally indicative of effective communication skills. The ability to maintain eye contact demonstrates engagement and social awareness, while the capacity to follow directions suggests a good understanding of language processing. A wide vocabulary typically signifies good expressive language skills, as it indicates a person's ability to express themselves in detail and with nuance. Therefore, the inability to articulate thoughts clearly stands out as a primary sign of an expressive language disorder.
