Question 1

Why do we use qué tan to mean "how" here instead of cómo?

Accepted Answer

When asking about the degree or extent of an adjective or adverb (like "how thick," "how fast," or "how far"), you can't translate "how" directly to cómo. In Latin America, the standard structure is qué tan followed by the adjective or adverb. Therefore, "how thick" becomes qué tan grueso.

Question 2

Can I use gordo instead of grueso to say "thick"?

Accepted Answer

Not in this case. Grueso is the correct word for the physical thickness, width, or depth of inanimate objects (like ice, walls, cables, or books). Gordo is generally used to mean "fat" or "overweight" when talking about people or animals.

Question 3

Since ice melts and its thickness can change, shouldn't we use está instead of es?

Accepted Answer

Even though a block of ice might eventually melt, basic physical dimensions—like thickness, height, and overall size—are treated as defining characteristics of the object as it currently exists, so we use ser (es). You would typically only use estar if you are emphasizing a surprising change from the norm, such as exclaiming ¡Qué grueso está el hielo hoy! (How thick the ice is today!).

Question 4

Why is it bloque de hielo instead of just hielo bloque like in English?

Accepted Answer

In Spanish, you cannot stack nouns together so that one acts as an adjective for the other (like "ice block" or "water bottle"). Instead, you must use the main noun (bloque) followed by the preposition de and then the material or category (hielo).
