Ella dirige el equipo.

Dirige is the 3rd person singular present indicative form of dirigir.

So:

• dirigir = to direct / to lead / to manage
• ella dirige = she directs / she leads / she manages

In this sentence, Ella dirige el equipo, the verb is in the present tense, so it means something like:

• She leads the team
• She manages the team
• She is in charge of the team

The exact English translation depends on context.

Yes. Spanish often drops subject pronouns because the verb ending already shows who the subject is.

So both of these are possible:

• Ella dirige el equipo.
• Dirige el equipo.

Both can mean She leads the team.

You include ella when you want to:

• add emphasis
• create contrast
  
  • Ella dirige el equipo, no él. = She leads the team, not him.
• make the subject extra clear

So ella is correct, but it is not always necessary.

In standard Peninsular Spanish, dirige is pronounced roughly like:

dee-REE-heh

A few key points:

• di sounds like dee
• the stress is on ri: di-RI-ge
• the g before e is pronounced like the Spanish j, a throaty sound similar to the ch in Scottish loch or German Bach

So it is di-RI-je, not with a hard English g sound.

Spanish uses the definite article el more often than English uses the.

So el equipo literally means the team.

In Spanish, this sounds natural:

• Ella dirige el equipo.

Even if English might sometimes say She leads a team or just She leads the team depending on context, Spanish often keeps the article.

Also:

• equipo is a masculine singular noun
• so it takes el

Not always. Dirigir can mean several related things, depending on context:

• to direct
  
  • dirigir una película = to direct a film
• to lead / manage / run
  
  • dirigir un equipo = to lead/manage a team
• to address
  
  • dirigir unas palabras = to address a few words
• to head toward / guide in some contexts

In Ella dirige el equipo, the most natural English meaning is usually:

• She leads the team
• She manages the team

It is mostly regular, but it has a spelling change in some forms.

Present tense:

• yo dirijo
• tú diriges
• él/ella dirige
• nosotros/nosotras dirigimos
• vosotros/vosotras dirigís
• ellos/ellas dirigen

The important thing to notice is:

• yo dirijo has j
• but forms like dirige keep g

This spelling change helps preserve pronunciation.

So in your sentence, dirige is a normal present-tense form of dirigir.

Because el equipo is the direct object, and it is not a specific person.

Spanish uses the personal a before a specific human direct object, for example:

• Veo a María. = I see María.

But here:

• Ella dirige el equipo.

el equipo is a thing/group, not treated as a person grammatically, so there is no personal a.

Yes, but Ella dirige el equipo is the most neutral and natural order.

Normal order:

• Ella dirige el equipo.

Other orders are possible, but they usually add emphasis or sound more marked:

• Dirige ella el equipo.
• El equipo lo dirige ella.

These are not the basic way a learner would usually say it. For most situations, stick with:

• Ella dirige el equipo.

It can sometimes refer to a present action, but the simple present in Spanish usually gives a more general meaning:

• Ella dirige el equipo. = She leads/manages the team

If you want to emphasize right now, at this moment, Spanish often uses:

• Ella está dirigiendo el equipo.

That means:

• She is leading/directing the team right now

So:

• dirige = simple present, often general or habitual
• está dirigiendo = happening right now

Usually, yes: ella means she.

So the sentence normally refers to a female person:

• Ella dirige el equipo. = She leads the team.

Very occasionally, pronouns can refer back to feminine nouns, but in a sentence like this, a learner should understand ella as she.

Here are the present-tense versions of dirigir with different subjects:

• Yo dirijo el equipo. = I lead the team.
• Tú diriges el equipo. = You lead the team.
• Él dirige el equipo. = He leads the team.
• Ella dirige el equipo. = She leads the team.
• Nosotros dirigimos el equipo. = We lead the team.
• Vosotros dirigís el equipo. = You all lead the team.
  
  • This is the common informal plural form in Spain.
• Ellos dirigen el equipo. = They lead the team.
• Ellas dirigen el equipo. = They lead the team.

If you are learning Spanish from Spain, vosotros dirigís is especially worth noticing.

The stress falls on the second syllable:

di-RI-ge

There is no written accent mark because it follows normal Spanish stress rules.

Words ending in a vowel, n, or s are normally stressed on the second-to-last syllable, and dirige fits that pattern.

Sometimes, yes.

• Ella dirige el equipo = She leads/manages the team
• Ella lidera el equipo = She leads the team

But they are not always identical.

• dirigir often suggests managing, running, being in charge of
• liderar focuses more directly on leading

With equipo, both can work, but dirige can sound a bit more like she runs/manages the team, while lidera is more straightforwardly she leads the team.
