La batalla terminó ayer.

In Spanish, nouns often use the definite article more than in English. La batalla means the battle.

• batalla = battle
• la batalla = the battle

You could say just batalla in some contexts, but in a full sentence like this, la batalla is the normal choice if you mean a specific battle.

Because batalla is a feminine noun in Spanish, so it takes the feminine singular article la.

A common clue is that nouns ending in -a are often feminine:

• la casa
• la guerra
• la batalla

This is a grammatical gender rule, not necessarily something connected to real-world gender.

Terminó is in the preterite tense, which is used for a completed action in the past.

So:

• termina = it ends / ends
• terminó = it ended

Since ayer means yesterday, the preterite is the natural tense here because the action happened at a finished point in the past.

The accent mark shows both pronunciation and meaning.

• termino = I end / I finish
• terminó = he/she/it ended

So the accent on -ó tells you this is the third person singular preterite form.

It also tells you the stress falls on the last syllable: ter-mi-NÓ.

The subject is la batalla.

So literally:

• La batalla = the battle
• terminó = ended
• ayer = yesterday

Spanish often does not need a separate subject pronoun like it, because the verb form already helps show the grammar. Here, the noun la batalla is already stated, so no pronoun is needed.

Spanish usually does not use a subject pronoun for things the way English does.

English says:

• The battle ended yesterday.

But if you replaced the battle with a pronoun, English would need it:

• It ended yesterday.

In Spanish, you would usually just say:

• Terminó ayer.

The verb ending often makes the subject pronoun unnecessary, especially when the context is clear.

Yes. Ayer terminó la batalla is also correct.

Spanish word order is more flexible than English. Both of these work:

• La batalla terminó ayer.
• Ayer terminó la batalla.

The difference is mostly one of focus:

• La batalla terminó ayer starts with the subject.
• Ayer terminó la batalla emphasizes yesterday a bit more.

In most of Spain, batalla is pronounced approximately bah-TAH-ya.

A rough guide:

• ba as in bah
• ta with the stress here: TA
• lla usually sounds like ya in most modern Spanish pronunciation

So:

• batalla ≈ bah-TAH-ya

In IPA, in standard modern pronunciation, it is often /baˈtaʝa/.

A simple approximate pronunciation is:

ter-mee-NOH ah-YEHR

A bit more carefully:

• terminó → stress on the last syllable: ter-mi-NÓ
• ayer → usually sounds like a-YER

So the full sentence is roughly: la ba-TA-ya ter-mi-NÓ a-YER

Ayer means yesterday.

It does not have to go at the end. Spanish allows some flexibility:

• La batalla terminó ayer.
• Ayer terminó la batalla.
• La batalla ayer terminó. — grammatically possible, but less natural in everyday speech

The most natural options are usually the first two.

Yes, often you can.

• La batalla terminó ayer.
• La batalla acabó ayer.

Both can mean The battle ended yesterday.

In many contexts, terminar and acabar overlap. However, depending on style or region, one may sound slightly more natural than the other. In this sentence, terminó is perfectly normal and clear.

Yes. Terminar is a regular -ar verb.

Its preterite endings are regular:

• terminé = I finished
• terminaste = you finished
• terminó = he/she/it finished
• terminamos = we finished
• terminasteis = you all finished
• terminaron = they finished

So terminó follows a very common pattern.

The personal a is only used before specific people (and sometimes pets or personified beings) when they are a direct object.

Example:

• Veo a María.

But in La batalla terminó ayer, there is no direct object at all. La batalla is the subject, so no personal a is needed.

Not exactly. Terminó ayer most directly means ended yesterday.

If you want was over yesterday, Spanish would more naturally use something like:

• La batalla ya había terminado ayer in a specific context, or
• La batalla ya estaba terminada ayer, though that sounds more marked and context-dependent.

So terminó ayer points to the moment of ending, not just the state after the end.
