May polusyon sa kapaligiran.

Here, may means there is or there exists. It is used to say that something is present.

So May polusyon sa kapaligiran means that pollution exists in the environment.

This is one of the most common uses of may in Filipino.

Filipino does not always use a direct equivalent of the English verb to be in the same way English does.

In this sentence, may works as an existential marker. It tells you that something exists or is present.

So instead of building the sentence like:

The environment is polluted

the Filipino sentence is built more like:

There is pollution in the environment

That is why may comes first.

Because polusyon is being introduced as something that exists, not as a specifically identified topic.

After may, nouns often appear without ang.

So:

• May polusyon = There is pollution
• not May ang polusyon = incorrect

In this structure, polusyon is indefinite and general, so no ang is needed.

Sa is a very common preposition that can mean in, on, at, to, or into, depending on context.

Kapaligiran means environment or surroundings.

So sa kapaligiran literally means in the environment or in the surroundings.

In this sentence, sa is best understood as in.

Kapaligiran refers to the environment, surroundings, or the area around us.

It comes from paligid, which means around or surrounding area.

So kapaligiran has the sense of one’s surroundings or the environment as a whole.

In everyday Filipino, it is a standard word for environment, especially in school, formal writing, and discussions about nature or pollution.

Not exactly, though they are related.

• kapaligiran = environment / surroundings
• kalikasan = nature

So:

• May polusyon sa kapaligiran = pollution exists in the environment
• May polusyon sa kalikasan could also be understood, but it sounds more like pollution affecting nature

In many contexts they overlap, but kapaligiran is the more direct match for environment.

Yes.

These are all natural:

• May polusyon sa kapaligiran
• Mayroong polusyon sa kapaligiran
• Merong polusyon sa kapaligiran

Differences:

• may is short and very common
• mayroon / mayroong is a fuller form and can sound a bit more formal or emphatic
• meron / merong is a very common spoken variant

All of them can mean the same thing here.

In Filipino, nouns do not usually change form for singular or plural the way English nouns do.

So polusyon stays polusyon.

Also, pollution is usually treated like an uncountable noun in English, and it works similarly here as a general idea or condition.

If you wanted to make plurality clearer with countable nouns, Filipino often uses context or words like mga. But with polusyon, that is usually unnecessary because it is a mass noun.

The most natural order here is:

May + noun + location

So:

May polusyon sa kapaligiran.

That is the standard and best version.

You may see other structures in Filipino, but for a basic existential sentence, this order is the normal one.

For example, Sa kapaligiran may polusyon is possible in some contexts for emphasis, but it sounds marked. A learner should treat May polusyon sa kapaligiran as the default form.

A simple pronunciation guide would be:

May = like English my
polusyon = po-lu-SYON
sa = sah
kapaligiran = ka-pa-li-GI-ran

A rough full pronunciation:

my po-lu-SYON sah ka-pa-li-GI-ran

The stress is commonly heard on:

• polusYON
• kapaliGIran

It is neutral and completely natural.

It works well in:

• school writing
• news-style language
• environmental discussions
• everyday statements

It is neither overly formal nor slangy.

Yes, that is possible as a literal way to think about it, because may can also express possession in some contexts.

However, the most natural English translation is still:

There is pollution in the environment.

That is the best way to understand the sentence as a learner.

You would usually replace may with walang.

So:

• May polusyon sa kapaligiran. = There is pollution in the environment.
• Walang polusyon sa kapaligiran. = There is no pollution in the environment.

This is a very useful pattern:

• may = there is / there are
• wala / walang = there is no / there are no
