Suriin ang langis, baterya, radiator, at transmisyon.

Suriin means check, inspect, or examine.

It is the command / imperative form of the verb suriin, which comes from the root suri meaning inspection or to inspect/analyze. In this sentence, it is telling someone to do the action:

• Suriin = Check / Inspect

So the whole sentence is giving an instruction.

In Filipino, it is very common for the verb to come first, especially in commands and many ordinary statements.

So instead of structuring it like English Check the oil, battery, radiator, and transmission, Filipino naturally says:

• Suriin = check
• ang langis, baterya, radiator, at transmisyon = the oil, battery, radiator, and transmission

This verb-first order is normal and natural in Filipino.

Ang is a very common marker in Filipino. In this sentence, it marks the noun phrase that the action is focused on.

Here, ang introduces the things being checked:

• ang langis, baterya, radiator, at transmisyon

A useful beginner-level way to think about it is that ang often points to the main noun or nouns being talked about in the sentence.

In this command, it helps mark the set of items that should be inspected.

Because ang can mark the entire list, not just the first noun by itself.

So:

• ang langis, baterya, radiator, at transmisyon

means that the whole series belongs together as one marked group.

You do not need to repeat ang before every item. Repeating it would sound unnatural in a simple list like this.

Mga is often used to mark plurality, but it is not required when the plural meaning is already obvious.

In this sentence, the speaker lists several separate items:

• oil
• battery
• radiator
• transmission

Since the list already clearly shows there is more than one thing, mga is unnecessary.

So ang langis, baterya, radiator, at transmisyon is perfectly natural.

At means and.

In Filipino lists, just like in English, the last two items are commonly connected with and:

• langis, baterya, radiator, at transmisyon
• oil, battery, radiator, and transmission

So at is simply the normal word for and here.

Filipino has borrowed many words from other languages, especially Spanish and English.

In this sentence:

• baterya comes from a borrowed form related to battery
• radiator is essentially the same as English
• transmisyon is a borrowed/adapted form of transmission

This is very common in Filipino, especially for technology, vehicles, and modern objects.

Langis is a native Filipino word meaning oil.

So the sentence mixes a native word with borrowed ones:

• langis = oil
• baterya = battery
• radiator = radiator
• transmisyon = transmission

This kind of mixing is very normal in Filipino vocabulary.

Yes. Suriin can be translated in several similar ways depending on context, such as:

• check
• inspect
• examine
• look over

For a car-maintenance context, check or inspect both work well.

It sounds neutral and standard. It works well for instructions, manuals, signs, or spoken advice.

It is not especially slangy, and it is not overly formal either. It fits practical situations such as:

• vehicle maintenance instructions
• a checklist
• a mechanic giving advice
• a safety reminder

Yes. Suriin is a general verb for examining or checking something carefully.

For example, it can be used for:

• documents
• reports
• machines
• evidence
• schoolwork
• medical results

So its meaning is broader than just car-related checking.

You can make it more polite by adding po or by changing the structure slightly.

For example:

• Pakisuri ang langis, baterya, radiator, at transmisyon.
• Pakisuri po ang langis, baterya, radiator, at transmisyon.

Here:

• paki- adds a polite please
• po adds respect

The original sentence is a straightforward command, while these versions sound more polite.

A simple pronunciation guide is:

• su-RI-in

You can think of it as three parts:

• su
• ri
• in

The stress is usually on ri.

Also, the ending is pronounced separately, so it is closer to su-ri-in than to a single-syllable English ending.

In standard Filipino, that would sound incomplete or unnatural.

The marker ang is important here because it marks the noun phrase being focused on. So the natural sentence is:

• Suriin ang langis, baterya, radiator, at transmisyon.

Leaving out ang would generally not be correct in this kind of sentence.

Yes. The punctuation follows a normal list pattern, much like English:

• item 1, item 2, item 3, and item 4

So:

• langis, baterya, radiator, at transmisyon

The commas separate the items, and at joins the last one. This is standard and easy to read.
