What can poor vocabulary contribute to in learners?

Poor vocabulary can significantly hinder a learner's ability to understand and engage with content, directly leading to poor comprehension. When students encounter texts or verbal information filled with words they do not know or understand, their ability to grasp the meaning or context diminishes. This lack of understanding can make it difficult to follow discussions, complete assignments, or engage critically with materials. A limited vocabulary directly impacts how well learners can process information, analyze concepts, and draw connections between ideas, which are all essential skills for successful learning.
