Which question word translates the sentence "He doesn't realize how wonderful he is"?

The sentence "He doesn't realize how wonderful he is" expresses a sense of admiration or an assessment of someone's qualities. In Latin, the word "quam" is utilized effectively to convey the idea of emphasis or intensity regarding the quality being described. It is often translated as "how" in the context of expressing degree, particularly when describing an adjective, such as "wonderful" in this case.

Using "quam" here highlights the extent of his wonderfulness, aligning perfectly with the original sentence's intention. The other question words do not fit the context as they serve different purposes: "cūr" means "why," which does not relate to the description of qualities, "quālis" translates to "what kind of" and might imply categorization rather than intensity, and "quot" refers to "how many," which is unrelated to the qualitative assessment required in this context. Thus, "quam" is the ideal choice to convey the intended meaning of the original sentence.
