Ella tiene suerte hoy.

Yes. Spanish often leaves subject pronouns out because the verb already shows who the subject is.

• (Ella) tiene suerte hoy. = She is lucky today.

Including ella can add emphasis, contrast, or clarity. For example:

• Ella tiene suerte hoy, pero yo no.
  She is lucky today, but I’m not.

In everyday Spanish, especially in conversation, Tiene suerte hoy is often completely natural if the subject is already clear from context.

This is just a very common Spanish way to express the idea. Spanish often uses tener suerte literally to have luck where English uses to be lucky.

So:

• Ella tiene suerte hoy. = She is lucky today.
• Literally: She has luck today.

Spanish can also use adjectives like afortunada or suertuda, but tener suerte is one of the most common and natural ways to say this.

Tiene is the third-person singular present tense form of tener.

The present-tense forms of tener are:

• yo tengo
• tú tienes
• él/ella/usted tiene
• nosotros tenemos
• ustedes/ellos/ellas tienen

So in Ella tiene suerte hoy, tiene matches ella.

Because tener is the infinitive, meaning to have. After a subject like ella, you need the conjugated form:

• ella tiene = she has

You would only use tener in places where English would use to have, such as:

• Quiero tener suerte. = I want to have luck / I want to be lucky.

After tener, Spanish often uses nouns without an article when talking about general states or qualities.

So:

• tener suerte = to be lucky / to have luck
• tener miedo = to be afraid / to have fear
• tener hambre = to be hungry
• tener razón = to be right

You can say la suerte in other contexts, where you mean luck as a noun:

• La suerte es importante. = Luck is important.
• Tuvo la suerte de conocerla. = He had the luck/good fortune to meet her.

But in the fixed expression tener suerte, no article is normally used.

Yes, hoy can move around. Spanish word order is flexible, especially with time expressions.

All of these are possible:

• Ella tiene suerte hoy.
• Hoy ella tiene suerte.
• Ella hoy tiene suerte.
• Hoy tiene suerte.

The version with hoy at the end sounds very natural and neutral. Putting hoy earlier can add a little emphasis to today.

A simple pronunciation guide:

• Ella ≈ EH-yah in many parts of Latin America, though pronunciation varies by region
• tiene ≈ TYEH-neh
• suerte ≈ SWEHR-teh
• hoy ≈ oy

Important notes:

• The h in Spanish is silent, so hoy does not sound like English hoy with an h sound. It is just oy.
• In tiene, the ie is part of a stem change from tener.

Yes, suerte is a feminine noun:

• la suerte

That matters when you use articles or adjectives with it:

• buena suerte = good luck
• mala suerte = bad luck
• la suerte = luck

But in tiene suerte, you do not see the article, so the femininity is less visible in the sentence itself.

Yes. Ella es afortunada hoy is grammatical and means roughly the same thing.

But there is a slight difference in feel:

• tiene suerte = she has luck / she’s lucky
• es afortunada = she is fortunate

Tiene suerte is very common and everyday.
Es afortunada can sound a bit more formal or descriptive.

Also, afortunada must agree with ella, so it ends in -a.

It exists, and in some places it is common, but it depends on the country and region.

• Ella es suertuda. = She is lucky.

However, tener suerte is broadly understood and very natural across the Spanish-speaking world, so it is usually the safest choice for learners.

A speaker might include ella for one of these reasons:

1. Contrast

   • Ella tiene suerte hoy, él no.

2. Emphasis

   • Ella tiene suerte hoy could stress that she, specifically, is the lucky one.

3. Clarity

   • If several people are being discussed, saying ella helps avoid confusion.

Without a special reason, Spanish often prefers the shorter version:

• Tiene suerte hoy.
