Ya he terminado la tarea.

Ya adds the idea of already. It emphasizes that the action is completed at this point.

So:

• He terminado la tarea = I have finished the homework / I finished the homework
• Ya he terminado la tarea = I have already finished the homework

In everyday Spanish, ya is very common when you want to show that something is done, often sooner than expected or simply by now.

He terminado is the present perfect:

• he = present tense of haber
• terminado = past participle

In Spain, this tense is very commonly used for actions connected to the present, especially with words like ya, hoy, esta semana, etc.

So in Spain:

• Ya he terminado la tarea sounds very natural.

A native English speaker might expect a simple past too, and Ya terminé la tarea is also understandable, but in many parts of Spain the present perfect is more typical in this kind of context.

He is the first-person singular form of haber in the present tense.

In this sentence, haber is not being used with its original meaning. It is acting as an auxiliary verb, helping to form the present perfect.

The pattern is:

• he = I have
• terminado = finished

So he terminado = I have finished

Be careful: this he is not related to the English pronoun he.

Because the subject is I.

The present tense of haber used for the present perfect is:

• he = I have
• has = you have
• ha = he/she/it has
• hemos = we have
• habéis = you all have
• han = they have

So:

• Yo he terminado = I have finished
• Ella ha terminado = She has finished

Terminado is the past participle of terminar.

For regular -ar verbs, the past participle ends in -ado:

• hablar → hablado
• estudiar → estudiado
• terminar → terminado

So:

• he terminado = I have finished

In this sentence, terminado is part of the verb phrase, not just an adjective.

Spanish often uses the definite article where English might not.

Here, la tarea means the homework or the assignment, even though in English we often just say homework without the.

This is normal Spanish usage. The article makes the noun sound complete and natural.

So:

• la tarea = the homework / the assignment

Without the article, tarea would usually sound incomplete in this sentence.

Yes, you can. It is grammatically correct.

However, Spanish often omits subject pronouns when they are not needed, because the verb already shows who the subject is.

So the more natural default is:

• Ya he terminado la tarea

You might include yo only for emphasis, contrast, or clarity:

• Yo ya he terminado la tarea, pero él no.
  = I have already finished the homework, but he has not.

Yes. Spanish word order is flexible, although some versions sound more natural than others depending on context.

Common possibilities include:

• Ya he terminado la tarea.
• He terminado ya la tarea.
• He terminado la tarea ya.

The first one is probably the most neutral and common.

Putting ya in a different position can slightly change the rhythm or emphasis, but the basic meaning stays the same.

Put no before the conjugated verb:

• No he terminado la tarea.
  = I have not finished the homework.

If you want to say I haven’t finished the homework yet, Spanish often uses:

• Todavía no he terminado la tarea.

That is a very common pattern:

• todavía no = not yet

You can turn it into a question by raising your intonation in speech or using question marks in writing:

• ¿Ya has terminado la tarea?
  = Have you finished the homework already?

If you want to ask about yourself, which is less common unless talking to yourself or checking something rhetorically, it would be:

• ¿Ya he terminado la tarea?

But normally you would ask another person, so has terminado is more useful.

It usually means the homework is finished by now, with a clear connection to the present.

That is why the present perfect is used. The exact time is not the focus; the important idea is the current result: the homework is done.

So the sentence often implies:

• it is completed now
• that matters now

Not in this sentence.

With haber + past participle, the participle does not change to match gender or number:

• He terminado la tarea
• He terminado los ejercicios
• He terminado la lección

It stays terminado.

Agreement happens more often when the participle is used as an adjective or with estar:

• La tarea está terminada.
  = The homework is finished.

Here, terminada agrees with tarea because it is describing the noun.

Yes, possibly.

In much of Spain, Ya he terminado la tarea is very natural for a recent completed action or one connected to the present.

In many parts of Latin America, speakers often prefer the simple past in the same situation:

• Ya terminé la tarea.

Both are correct Spanish, but the preferred tense can vary by region. Since your sentence is specifically Spanish from Spain, ya he terminado la tarea is exactly the kind of structure learners should expect to hear there.
