Hindi aandar ang makina maliban kung maayos ang baterya.

Hindi is the normal Filipino word for not when negating statements.

So in Hindi aandar ang makina, hindi negates the verb phrase and gives the idea the engine will not run / will not start.

It usually comes before what it negates:

• Hindi ako pagod. = I am not tired.
• Hindi umuulan. = It is not raining.
• Hindi aandar ang makina. = The engine will not run.

Andar is the root word, related to movement or running/operating. In this sentence, aandar is the inflected form meaning will run, will work, or will start running depending on context.

The form aandar shows a contemplated or future action. A very rough comparison is:

• andar = the root idea run / operate
• umaandar = is running / is operating
• aandar = will run / will operate

So:

• Umaandar ang makina. = The engine is running.
• Aandar ang makina. = The engine will run.

That extra syllable is part of a common Filipino verb pattern called reduplication. For many verb forms, the first consonant-vowel part of the root gets repeated.

With the root andar, the form becomes a-andar, written aandar.

This often signals a contemplated or not-yet-completed action:

• alis → aalis = will leave
• akyat → aakyat = will go up
• andar → aandar = will run

So the doubled beginning is not random; it is a normal grammatical pattern.

Ang is a marker for the focused noun phrase, often the topic or what English speakers loosely think of as the subject.

In the first clause:

• Hindi aandar ang makina
• ang makina = the engine

In the second clause:

• maayos ang baterya
• ang baterya = the battery

A helpful beginner-level way to read this is:

• aandar ang makina = the engine will run
• maayos ang baterya = the battery is okay / in good condition

So ang tells you which noun phrase is being highlighted as the main participant in that clause.

Filipino often puts the predicate first. English usually prefers subject + verb, but Filipino very often uses predicate + subject/topic order.

So instead of:

• The engine will not run

Filipino naturally says:

• Hindi aandar ang makina

And instead of:

• The battery is okay

Filipino naturally says:

• Maayos ang baterya

This predicate-first structure is extremely common in Filipino, so it is something learners need to get used to.

Maliban kung means unless.

It literally works like except if:

• maliban = except
• kung = if

So:

• Hindi aandar ang makina maliban kung maayos ang baterya. means
• The engine will not run unless the battery is okay.

You can think of maliban kung as a fixed expression meaning unless, even though its parts are understandable separately.

Kung usually means if.

In this sentence, it appears inside the expression maliban kung, which means unless.

By itself:

• Kung maayos ang baterya, aandar ang makina. = If the battery is okay, the engine will run.

Inside the full expression:

• maliban kung maayos ang baterya = unless the battery is okay

So kung is the conditional word that introduces the condition.

Maayos means something like in good condition, properly fixed, okay, orderly, or working properly, depending on context.

In this sentence, maayos ang baterya most naturally means:

• the battery is okay
• the battery is in good condition
• the battery is properly connected / functioning properly

It comes from the root ayos, which has to do with order, arrangement, fixing, or being proper.

So maayos describes the battery’s condition.

Filipino often does not need a separate word for is/are in simple equational or descriptive sentences.

So:

• Maayos ang baterya. literally looks like
• Okay the battery but it means
• The battery is okay.

This is very normal in Filipino:

• Maganda ang bahay. = The house is beautiful.
• Mabait siya. = He/She is kind.
• Maayos ang baterya. = The battery is okay.

So the idea of is is understood from the sentence structure.

Filipino does not use articles in the same way English does.

The marker ang does not exactly equal the, but in many simple translations it often comes out that way:

• ang makina ≈ the engine
• ang baterya ≈ the battery

Whether something is the, a, or just a general noun often depends on context rather than on a separate article system like English.

So it is better not to assume:

• ang = the in a strict one-to-one way

But for this sentence, translating ang makina and ang baterya as the engine and the battery is perfectly natural.

Yes. The root andar can refer to movement or operation, so its exact translation depends on context.

For machines, vehicles, and engines, aandar often means:

• will run
• will operate
• will start
• will work

Because the noun here is makina (engine), the meaning is about operating, not just physical movement.

So in this sentence, aandar ang makina is best understood as:

• the engine will run or
• the engine will start working

That is a voice and verb-focus difference.

Aandar is intransitive or actor-focused in sense here: the engine itself will run/operate.

Iandar or paandarin would usually involve causing something to run or start, more like:

• to make it run
• to start it
• to operate it

Compare:

• Aandar ang makina. = The engine will run.
• Paandarin mo ang makina. = Start the engine. / Make the engine run.

So aandar is the correct choice when the engine itself is the thing being described as running.

Yes, it is natural and grammatical.

It sounds like a practical, everyday statement about a machine or vehicle. The structure is clear:

• Hindi aandar ang makina = The engine will not run
• maliban kung maayos ang baterya = unless the battery is okay

A Filipino speaker might also say similar versions depending on context, such as using more specific wording for the battery problem, but your sentence is perfectly normal and understandable.

Yes. Maayos ang baterya is a bit broad.

Depending on the situation, it could mean:

• the battery is in good condition
• the battery is properly installed
• the battery connection is okay
• the battery is working properly

If someone wanted to be more specific, they might choose a more exact phrase. But maayos ang baterya is a natural general way to say the battery must be okay for the engine to run.

A very helpful breakdown is:

• Hindi = not
• aandar = will run / will operate
• ang makina = the engine
• maliban kung = unless
• maayos = okay / in good condition
• ang baterya = the battery

So the sentence structure is:

Hindi aandar ang makina

• maliban kung maayos ang baterya

That makes it easier to see that it contains two clauses:

1. The engine will not run
2. unless the battery is okay
