La actriz firma el aviso.

Because actriz is a feminine noun meaning a female actor, so it takes the feminine article la.

A useful pattern is:

• el actor = the actor
• la actriz = the actress

Even though many feminine nouns end in -a, not all of them do. Actriz is feminine even though it ends in -z.

Firma is the third-person singular present tense form of firmar.

That means it matches subjects like:

• él = he
• ella = she
• usted = you (formal)

So in this sentence, firma matches la actriz.

Basic conjugation of firmar in the present:

• yo firmo = I sign
• tú firmas = you sign
• él/ella/usted firma = he/she/you sign

Spanish often leaves out subject pronouns because the verb ending already tells you who the subject is.

So instead of saying:

• Ella firma el aviso

Spanish very naturally says:

• La actriz firma el aviso

or even just:

• Firma el aviso

if the context already makes the subject clear.

Adding ella is possible, but it usually adds emphasis, contrast, or clarity.

Because aviso is a masculine noun, so it takes el.

• el aviso = the notice / the announcement / the warning

This is also a good reminder that noun gender in Spanish is something you often have to learn with the noun itself. In this case, aviso ends in -o, which is commonly masculine.

Aviso can mean different things depending on context, such as:

• notice
• announcement
• warning
• ad

In this sentence, the exact English choice depends on the context you were given. Spanish words often cover a wider range of meanings than a single English word.

So the grammar stays the same, even if the best translation of aviso changes by situation.

Spanish uses articles very often with nouns, especially when the speaker means a specific person or thing.

Here:

• la actriz refers to a specific actress
• el aviso refers to a specific notice/announcement/warning

Spanish usually sounds more natural with the article in cases like this. English sometimes omits articles in places where Spanish keeps them, but in this sentence both languages normally use them.

Great question, because firma can also be a noun in Spanish.

It can mean:

• signature
• sometimes company/firm in other contexts

But in La actriz firma el aviso, firma is clearly a verb because of its position and structure:

• La actriz = subject
• firma = verb
• el aviso = direct object

So the sentence follows the common pattern:

subject + verb + object

Yes, Spanish word order is more flexible than English, but La actriz firma el aviso is the most neutral and natural order.

This is the standard pattern:

• subject + verb + object

You might see other orders in special contexts for emphasis, style, or literature, but for a learner, this version is the best basic model.

For example:

• La actriz firma el aviso. = neutral
• El aviso lo firma la actriz. = emphasizes that it is the notice that the actress signs

So yes, word order can change, but not randomly.

In Latin American Spanish, actriz is pronounced roughly like:

• ahk-TREES

A few helpful notes:

• The stress is on the last syllable: -triz
• The z in Latin America sounds like s
• So actriz sounds close to ak-TREES

Its plural is:

• actrices = actresses

Yes. That would also be correct, but it changes the feel slightly.

• La actriz firma el aviso = simple present; can mean the actress signs the notice or sometimes is signing, depending on context
• La actriz está firmando el aviso = emphasizes that the action is happening right now

Spanish uses the simple present more broadly than English sometimes does, so firma can already work in situations where English might prefer is signing.

The infinitive is firmar, and yes, it is a regular -ar verb.

That makes it easier to learn because it follows the normal present-tense pattern for -ar verbs.

For example:

• firmo
• firmas
• firma
• firmamos
• firman

So once you know regular -ar endings, firmar is straightforward.
