What level of understanding involves being able to give a definition and examples of a word?

The correct answer is based on the idea that deep knowledge of a word encompasses not only the ability to define it but also to provide relevant examples that illustrate its use in different contexts. This level of understanding means that the individual has moved beyond just recognition or basic recall of the word; they can articulate its meaning and demonstrate comprehension through examples. Such an understanding suggests the person has engaged with the word in a meaningful way, potentially considering its connotations and nuances.

In contrast, surface knowledge may imply a very basic awareness without in-depth understanding or the ability to apply it. Introductory knowledge suggests familiarity but not necessarily mastery. Visual recognition pertains to the ability to identify a word when seen visually, which does not require an understanding of its meaning or examples. Therefore, the capacity to define a word and provide examples is indicative of a deeper cognitive engagement with the language, aligning perfectly with the concept of deep knowledge.
