Gawin mo ang takdang-aralin bago manood ng pelikula.

Filipino sentences, especially commands, often start with the verb. So Gawin mo... is a very natural way to say Do it... or Do....

Here, gawin is the command form of the verb gawa meaning do/make.

This is about focus.

• gawin is an object-focus form
• gumawa is an actor-focus form

In this sentence, the thing being acted on is ang takdang-aralin, so gawin is the right choice.

A rough contrast:

• Gawin mo ang takdang-aralin = Do the homework
• Gumawa ka ng takdang-aralin would sound more like Make/do some homework with a different focus pattern

So gawin matches the structure used here.

Here, mo means you as the person being told to do the action.

It is the second-person singular pronoun in the non-ang set.

So:

• Gawin mo... = You, do...

Even though mo can also mean your in other sentences, here it is functioning as the doer, not as a possessor.

In this exact sentence, mo does not directly mean your homework. It marks the person who should do the homework.

Filipino often leaves possession unspoken if it is obvious from context. If someone tells you to do homework, it is normally understood to be your homework.

If you wanted to say it more explicitly, you could say:

• Gawin mo ang takdang-aralin mo

That version clearly includes your homework.

Ang is a marker that highlights the noun phrase that is in focus in the sentence.

Here, it marks:

• ang takdang-aralin = the homework

In English, there is no exact one-word equivalent for ang. You usually just learn how it works through sentence patterns.

Because the verb is gawin in object-focus, the thing being done takes ang.

Takdang-aralin is the usual Filipino word for homework.

Literally, it comes from words related to:

• takda = assigned/set
• aralin = lesson/study

So the idea is something like assigned lesson/work.

The hyphen is part of the standard spelling of this compound word.

Yes, bago can mean new, but in this sentence it means before.

Context tells you which meaning is intended.

Here:

• bago manood ng pelikula = before watching a movie

So this bago is a conjunction, not the adjective new.

After bago, Filipino commonly uses a verb form that works like English to watch or watching.

So:

• bago manood = before watching / before you watch

Manood is the actor-focus form of watch used here in a non-finite, infinitive-like way. Filipino does not need a separate word like English to before the verb.

Because manood is an actor-focus verb here, the thing being watched is marked with ng.

So:

• manood ng pelikula = watch a movie

This is a very common pattern in Filipino:

• actor-focus verb + ng object

If you used ang pelikula, the sentence structure would need to change.

It is understood to be the same person being addressed in the command: you.

So the full sense is:

• You should do the homework before you watch a movie

Filipino often leaves that subject unstated in the second clause when it is already clear from context.

The order here is the most neutral and natural:

• Gawin mo
  • ang takdang-aralin
    • bago manood ng pelikula

That said, Filipino word order is somewhat flexible, especially for emphasis. But for learners, this sentence is a good standard pattern to follow:

• verb
• doer pronoun
• ang-marked noun
• time/subordinate phrase

It is most naturally understood as a command or instruction.

That comes mainly from gawin, which here has an imperative feel: Do the homework...

Depending on tone and context, it could sound:

• firm
• parent-like
• instructional
• mildly advisory

But grammatically, it reads most naturally as a command.
