Suriin ang gulong at preno.

It is an imperative sentence, meaning it gives a command or instruction.

In English, it corresponds to something like:

• Inspect the tire and brake.
• Check the tires and brakes.

Filipino often uses this kind of form in manuals, instructions, reminders, and safety notices.

Suriin comes from the root word suri, which means inspection, examination, or to inspect/examine.

The -in ending is a common verbal form in Filipino. In this sentence, suriin functions as a command meaning:

• inspect
• examine
• check carefully

So suriin is not just the bare root; it is a verb form used here to tell someone to do the action.

Ang marks the noun phrase that is the main focus or target of the action in the sentence.

In Suriin ang gulong at preno, the things being inspected are:

• ang gulong at preno = the wheel/tire and brake or the wheels/tires and brakes, depending on context

So ang is marking the things that should be inspected.

Because gulong at preno is treated as one coordinated noun phrase:

• ang gulong at preno = the wheel/tire and brake

You do not need to repeat ang before each noun when they are joined by at (and).

That said, repeating it is sometimes possible in other contexts for emphasis or structure, but here the natural phrasing is:

• ang gulong at preno

At means and.

So:

• gulong at preno = wheel/tire and brake

It simply connects the two nouns.

It can mean wheel and is also often used in everyday contexts to refer to a tire, depending on the situation.

So in a sentence like this, especially in a vehicle-safety context, gulong may be understood as:

• wheel
• tire
• sometimes even wheels/tires in a general sense

Context tells you which English word sounds most natural.

Preno is a loanword, ultimately from Spanish freno, meaning brake.

Loanwords are very common in Filipino, especially for everyday objects, transportation, tools, and technology.

Filipino nouns usually do not change form for singular vs. plural the way English nouns do.

So:

• gulong can mean wheel or wheels
• preno can mean brake or brakes

The exact number depends on context.

If a speaker wants to make plurality explicit, they can use mga:

• ang mga gulong at preno = the wheels/tires and brakes

But in many practical instructions, leaving out mga is completely normal.

Verb-first word order is very common in Filipino.

So the pattern here is:

• Suriin = verb
• ang gulong at preno = the thing being inspected

This verb-initial structure is one of the basic patterns learners will see often in Filipino.

Yes. By itself, Suriin ang gulong at preno sounds like a plain instruction, which is normal for:

• signs
• manuals
• checklists
• official reminders

To make it more polite in direct conversation, speakers might add polite words such as:

• Pakisuri ang gulong at preno. = Please inspect the tire(s) and brake(s).
• Pakisuri po ang gulong at preno. = a more polite version with po

So the original is not rude; it is just straightforward and instructional.

A simple guide is:

• su-ri-in

You pronounce each vowel clearly. The ii is not reduced to one English-style vowel sound.

A rough English-friendly approximation is:

• soo-ree-een

But it is best to keep the vowels separate and clean:

• su-ri-in

Yes. That would be perfectly natural if you want to make it clearer that you mean multiple wheels/tires:

• Suriin ang mga gulong at preno.

This can sound more explicit in contexts like vehicle inspection. But the original sentence without mga is also natural and common, especially in short instructions.

Yes, but it depends on context.

• Inspect sounds a bit more formal, careful, or technical.
• Check sounds more everyday and general.

Because suriin suggests examining something, both can work. In safety or maintenance contexts, inspect may be closer. In ordinary usage, check may sound more natural in English.
