What can be a result of deficient vocabulary development?

Deficient vocabulary development can significantly hinder a student's ability to comprehend texts. When a learner lacks a robust vocabulary, they may struggle to understand the meaning of words and phrases in context, making it difficult to grasp the overall message or themes of a text. This limitation often leads to misunderstandings and a lack of engagement with the reading material. As vocabulary is crucial for making connections between concepts and ideas, insufficient word knowledge can directly impact a student's reading comprehension abilities, leading to challenges in both academic performance and everyday reading tasks.

In contrast, increased reading speed, improved word recognition skills, and enhanced critical thinking are outcomes typically associated with strong vocabulary development rather than deficiencies.
