Mataas ang hagdan.

Because Filipino often puts the predicate first.

In Mataas ang hagdan, the descriptive word mataas comes first, and the thing being described, hagdan, comes after it.

So the structure is roughly:

• mataas = high/tall
• ang hagdan = the stairs / the staircase

A very natural English-like rearrangement would be:

• The stairs are high.

But in Filipino, descriptions commonly come first.

Ang is a marker, not exactly a word like English the.

In this sentence, ang marks hagdan as the topic/focus noun of the sentence:

• Mataas = high
• ang hagdan = the stairs / the staircase

So ang helps show that hagdan is the thing being talked about.

It is often translated as the in simple sentences, but that is not its full job. Its grammatical role is more important than a direct one-word English translation.

In present-tense descriptive sentences, Filipino often does not use a copula like English is/are.

So:

• Mataas ang hagdan
  literally looks like
• High the stairs

But the natural English meaning is:

• The stairs are high.

This is completely normal in Filipino. The idea of is/are is understood without saying it.

It can be understood as stairs, staircase, or sometimes even ladder, depending on context.

Filipino nouns usually do not change form for singular vs. plural the way English nouns often do. So hagdan can refer to:

• a staircase
• stairs as a whole
• sometimes a ladder, depending on context

If you want to clearly mark plurality in Filipino, you can use mga, but with a word like hagdan, English often treats it as a single unit anyway.

Mataas usually means high or tall, not specifically steep.

So Mataas ang hagdan suggests that the stairs or staircase are high/tall, or that the steps are high. If you want to say the stairs are steep, a more precise word is:

• matarik = steep

So:

• Mataas ang hagdan = The stairs are high / the staircase is tall
• Matarik ang hagdan = The stairs are steep

This is a very common learner question because English sometimes uses high and steep in overlapping situations, but Filipino usually keeps them more separate.

Yes. That is also correct.

• Mataas ang hagdan
• Ang hagdan ay mataas

Both mean the same thing: The stairs are high.

The difference is mostly in style and structure:

• Mataas ang hagdan is a very common, natural predicate-first pattern.
• Ang hagdan ay mataas uses ay, which creates a more topic-first structure and can sound a bit more formal, careful, or textbook-like.

Both are good to know.

Mataas is an adjective.

It describes a quality of the noun:

• mataas = high / tall
• hagdan = stairs / staircase

In this sentence, the adjective is functioning as the predicate of the sentence, which is why it comes first.

No, not in the way they do in many European languages.

Mataas stays mataas whether the noun is singular, plural, masculine, feminine, or anything else.

So you do not need to memorize different adjective endings. That makes Filipino adjectives much simpler in this respect than adjectives in languages like Spanish or French.

It is pronounced roughly like hag-DAN, with the stress on the second syllable.

A simple approximation for English speakers is:

• hag
  • DAHN

Try to pronounce both consonants clearly in the middle:

• hagdan, not hadan

And mataas is roughly:

• ma-ta-AS

with the stress near the end.

It is grammatical and understandable, but whether it sounds perfectly natural depends on the context.

For example:

• If you mean the staircase is tall/high, it works.
• If you mean the steps are unusually high, it can also work.
• If you really mean the stairs are steep, then matarik is usually better.

So the sentence is correct, but in real life Filipino speakers might choose a more specific word depending on exactly what they mean.

You use hindi:

• Hindi mataas ang hagdan.

This means:

• The stairs are not high.

A very common pattern is:

• Hindi + predicate + ang + noun

So:

• Mataas ang hagdan. = The stairs are high.
• Hindi mataas ang hagdan. = The stairs are not high.

This is a useful vocabulary distinction.

• hagdan = the whole staircase / stairs / ladder
• baitang = one step or rung

So if you want to talk about the whole set of stairs, use hagdan.
If you want to talk about the individual steps, use baitang.

For example, if the issue is that each step is too high, a speaker might choose wording that refers to the baitang instead of the whole hagdan.
