Nasa kanan ng pinto ang basurahan.

Nasa shows location. In this sentence, it means something like is at / is in / is located at.

So:

• Nasa kanan = is on the right
• Nasa kanan ng pinto = is to the right of the door

A useful way to think about it is:

• sa = at / in / on / to
• nasa = often used when saying where something is

In everyday Filipino, nasa is extremely common for location statements.

Because Filipino often puts the predicate or location phrase first.

So the structure here is:

• Nasa kanan ng pinto = location/predicate
• ang basurahan = the thing being talked about

Literally, it is closer to:

• On the right of the door is the trash can.

That sounds unusual in English, but it is very natural in Filipino.

If you want a version that feels closer to English word order, you can also say:

• Ang basurahan ay nasa kanan ng pinto.

Both are correct. The original sentence is just a very natural Filipino word order.

Kanan means right as a direction.

So:

• sa kanan = on the right / to the right

This is a fixed and very common expression for location.

Examples:

• sa kaliwa = on the left
• sa kanan = on the right
• sa harap = in front
• sa likod = behind / at the back

In this sentence, sa kanan ng pinto means to the right of the door.

Here, ng links kanan to pinto and gives the meaning of the door.

So:

• kanan ng pinto = the right side of the door / the right of the door

This ng is not the same as the English preposition of in every situation, but here that is the easiest way to understand it.

Compare:

• ang pinto = the door as the main topic/focus
• sa pinto = at the door
• ng pinto = of the door

So if you said sa pinto, the meaning would change. The sentence is not saying the trash can is at the door; it is saying it is to the right of the door.

Yes. Basurahan commonly means trash can, garbage bin, or wastebasket, depending on context.

It comes from:

• basura = trash / garbage
• -han = a suffix that often refers to a place or container associated with something

So basurahan is literally something like:

• a place/container for trash

That is why it means trash can or garbage bin.

Yes, absolutely.

These two are both correct:

• Nasa kanan ng pinto ang basurahan.
• Ang basurahan ay nasa kanan ng pinto.

The difference is mostly about style and emphasis.

• Nasa kanan ng pinto ang basurahan.
  More naturally predicate-first; very common in Filipino.
• Ang basurahan ay nasa kanan ng pinto.
  Puts ang basurahan first, which may feel easier for English speakers.

The meaning is the same.

It comes from the whole phrase:

• sa kanan ng pinto

Breaking it down:

• sa = at/on/to
• kanan = right side
• ng pinto = of the door

So literally it is something like:

• at the right side of the door

Natural English turns that into:

• to the right of the door

So there is no separate Filipino word here that exactly matches English to in to the right of. The whole phrase carries that meaning.

Ang marks the noun phrase that is being highlighted as the main grammatical focus of the sentence.

Here:

• ang basurahan = the trash can

In simple learner-friendly terms, ang often marks the main thing being talked about.

In this sentence, the location comes first, and then ang basurahan identifies what is in that location.

So the sentence is not just a string of words; it is organized like this:

• Nasa kanan ng pinto = where it is
• ang basurahan = what it is

Use sa when you just need the preposition at / in / on / to inside a larger phrase.

Examples:

• sa bahay = at home / in the house
• sa mesa = on the table

Use nasa very often when you are making a full statement about where something is.

Examples:

• Nasa bahay siya. = He/She is at home.
• Nasa mesa ang libro. = The book is on the table.

So in your sentence:

• Nasa kanan ng pinto ang basurahan.
  = The trash can is to the right of the door.

A good beginner rule is:

• sa = location marker
• nasa = is located at/in/on

That rule is not perfect for every advanced case, but it works well for this sentence.

In this sentence, kanan clearly means right side as the opposite of left.

English uses right for two ideas:

• direction: right vs left
• correctness: right vs wrong

Filipino usually does not use kanan for correct.

• kanan = right side
• tama = correct / right

So here, there is no ambiguity:

• sa kanan ng pinto = to the right of the door

Yes. It is a complete sentence.

Filipino often does not need a separate word exactly equivalent to English is in the same way English does. The sentence structure itself expresses the relationship.

Here, nasa already carries the location idea, so the sentence is fully complete:

• Nasa kanan ng pinto ang basurahan.

You do not need to add another word for is.

That is very normal in Filipino.
