Question 1

I learned that ما means "what?" in questions or "not" with verbs. What is it doing in this sentence?

Accepted Answer

Here, ما is used to make an exclamation! When you combine ما with a word on the أفعل (afʿal) pattern—which usually makes comparative adjectives like "bigger" or "greater"—it translates to "What a...!" or "How...!". So, ما أعظم means "What a great...!" or "How great!".

Question 2

Is أعظم acting as a comparative adjective here?

Accepted Answer

It looks exactly like the comparative adjective for "greater", but in this specific exclamation structure (ما أفعل), it actually functions as a past-tense verb! Because it acts as a verb, it takes a direct object, which is why the phrase that follows it is technically in the accusative case (taking a fatha vowel at the end).

Question 3

Why does العرض have the definite article الـ attached to it?

Accepted Answer

This is an important rule for demonstrative pronouns like هذا (this). When "this" is followed by a definite noun (with الـ), they lock together into a phrase: هذا العرض means "this show". If you took off the الـ, it would become a complete sentence: هذا عرض (This is a show).

Question 4

Why does the adjective البصري (visual) also have الـ on it?

Accepted Answer

In Arabic, adjectives must copy the definiteness of the noun they describe. Because "the show" (العرض) is definite with الـ, its adjective "visual" (البصري) must also have الـ to match it properly.
