Isampay mo muna ang basa mong damit sa likod ng bahay bago umulan.

Sampay is the root word related to hanging up laundry/clothes.

Isampay is the verb form used here. The prefix i- often signals that the sentence is focused on the thing being put or placed somewhere. In this sentence, the thing being hung up is ang basa mong damit.

So:

• sampay = the root idea, hang up
• isampay = hang it/them up

In commands, isampay mo is a very natural way to say hang it up / hang them up.

Mo means you / your in a non-subject form.

In this sentence, mo marks the person doing the action:

• Isampay mo... = You hang up...

This happens because the verb is in a form where the thing affected by the action is marked with ang, not the doer. So:

• mo = the doer (you)
• ang basa mong damit = the thing being hung up

This is a very common Filipino sentence pattern.

Here, ang marks the noun phrase that the verb is focused on: ang basa mong damit.

Because the verb is isampay, the sentence is structured so that the clothes are the main item being acted on:

• Isampay mo = you hang up
• ang basa mong damit = the wet clothes

So ang is not exactly the same as English the, even though it is often translated that way. Its job here is more grammatical: it marks the focused noun phrase.

Muna usually means something like first, for now, or in the meantime.

In this sentence, it suggests:

• Do this first
• Hang them up before anything else

So Isampay mo muna... means something like:

• Hang up your wet clothes first...
• Go hang up your wet clothes for now...

It often makes a command sound a little more natural and less abrupt too.

Basa means wet, and damit means clothes/clothing.

The form mong is mo + -ng. The -ng is a linker, which connects words smoothly.

So:

• basa = wet
• mo = your
• damit = clothes

Together, basa mong damit means your wet clothes.

A useful way to think of it is that Filipino often links descriptive words and noun phrases together with -ng or na.

Yes, you can, and it would still sound natural.

Both can mean your wet clothes:

• basa mong damit
• basang damit mo

The difference is mostly in structure and emphasis, not in basic meaning.

Very roughly:

• basa mong damit highlights wet early
• basang damit mo feels like your clothes that are wet

In everyday speech, both are possible. The sentence you were given is completely natural.

It means at the back of the house or behind the house, depending on context.

Breakdown:

• sa = in/at/to
• likod = back, rear
• ng bahay = of the house

So literally it is at the back of the house.

This is a very common Filipino way to express location.

In English, we say before it rains, using the dummy subject it.

In Filipino, you do not need a word like it for weather expressions. You can simply say:

• umulan = to rain / for rain to happen

So:

• bago umulan = before it rains

There is no need for a separate subject.

Here, umulan works well after bago to mean before it rains or before rain comes.

Very roughly:

• umuulan usually points more clearly to an ongoing action: it is raining
• umulan can work more like to rain / for rain to happen

So after bago, bago umulan is the natural choice for before it rains.

Here it means wet.

That is because basa in Filipino can mean two different things depending on context:

• basa = wet
• basa = read as a verb root

In basa mong damit, the noun is damit (clothes), so the natural meaning is wet clothes, not clothes you read.

Context makes the meaning clear.

Yes, Filipino word order is more flexible than English word order.

The original sentence is natural:

• Isampay mo muna ang basa mong damit sa likod ng bahay bago umulan.

But you could also hear variations such as:

• Isampay mo muna sa likod ng bahay ang basa mong damit bago umulan.

The meaning stays basically the same. The difference is usually just emphasis or flow.

The original version is clear and very normal, especially if the speaker wants to mention the thing to be hung up before the location.
