Nasa talyer ang tantiya at garantiya.

Nasa means is/are in, at, on in a location sense.

In this sentence, Nasa talyer means is/are at the workshop.

A useful way to think of it is:

• sa = in/at/on/to
• nasa = a very common form used when something is located somewhere

So:

• Nasa bahay ang susi. = The key is at home.
• Nasa talyer ang tantiya at garantiya. = The estimate and warranty are at the workshop.

Ang marks the topic or focus noun phrase of the sentence.

Here, ang tantiya at garantiya is one coordinated noun phrase: the estimate and warranty.

So the structure is:

• Nasa talyer = the predicate/location part
• ang tantiya at garantiya = the topic, the things being talked about

Even though there are two nouns joined by at, only one ang is needed because the whole phrase acts as one unit.

Because the phrase already clearly refers to more than one thing through tantiya at garantiya.

In Filipino, you do not always need mga just because the meaning is plural. Coordination already makes it plural enough.

So this is natural:

• ang tantiya at garantiya

Using mga here is usually unnecessary. The sentence already clearly means two items.

Because predicate-first word order is very common in Filipino.

So instead of starting with the estimate and warranty, Filipino often starts with the predicate:

• Nasa talyer ang tantiya at garantiya.

A more English-like reordered version is also possible:

• Ang tantiya at garantiya ay nasa talyer.

Both are grammatical, but the first one is very natural and common in everyday Filipino.

Sa talyer is just the location phrase at the workshop.

Nasa talyer means is/are at the workshop.

So:

• sa talyer = just a prepositional phrase
• nasa talyer = a full predicate meaning located at the workshop

Compare:

• Iniwan ko ang kotse sa talyer. = I left the car at the workshop.
• Nasa talyer ang kotse. = The car is at the workshop.

Nasa does not change for singular or plural.

Filipino verbs and predicate markers generally do not behave like English is/are in this way. The same form can work with one thing or more than one thing.

So both are fine:

• Nasa talyer ang kotse. = The car is at the workshop.
• Nasa talyer ang tantiya at garantiya. = The estimate and warranty are at the workshop.

English forces you to choose is or are, but Filipino does not do that here.

Talyer means workshop, and in many everyday contexts it especially refers to a repair shop, often an auto repair shop.

It comes from Spanish taller.

So if the sentence is about car repairs, talyer would often be understood as something like:

• repair shop
• garage
• workshop

The exact English translation depends on context.

They are commonly used Filipino words, but both are loanwords, historically from Spanish.

• tantiya = estimate, approximation, sometimes guess
• garantiya = guarantee or warranty

In practical contexts, especially repairs or services:

• tantiya can mean an estimated cost or estimate
• garantiya can mean a warranty/guarantee

Because ay is optional in this kind of sentence.

Filipino often uses the simpler predicate-first pattern without ay:

• Nasa talyer ang tantiya at garantiya.

You can also say:

• Ang tantiya at garantiya ay nasa talyer.

That version sounds a little more formal or carefully structured, but both are correct.

Yes. At is the standard word for and when joining words or phrases in a more neutral or formal way.

So:

• tantiya at garantiya = estimate and warranty

In casual speech, people also often use tsaka or at saka for and, but at is the straightforward choice in a sentence like this.

Yes. Even if the basic meaning stays the same, the most natural English wording can vary depending on context.

Possible translations include:

• The estimate and warranty are at the workshop.
• The estimate and the warranty are at the repair shop.
• The estimate and warranty are in the shop.

If the context is car repair, repair shop may sound more natural than workshop. If the context is general craft or mechanical work, workshop may fit better.
