Tienes razón. Lo siento de verdad. ¿Hacemos las paces?

In Spanish, the natural expression for you are right is tener razón — literally, to have reason.

• Tienes razón = You’re right
• No tienes razón = You’re not right / You’re wrong

Using ser correcto here would sound unnatural. Correcto is used more for things like answers, information, or procedures, not usually for telling a person they are right in an argument.

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

• Tienes clearly means you have (informal singular)
• So tú is not necessary

You could say Tú tienes razón if you want emphasis, for example:

• Tú tienes razón, no yo. = You’re right, not me.

But in a normal apology, Tienes razón sounds more natural.

Yes. Tienes is the tú form, so it is informal singular you.

If you were speaking formally, you would say:

• Tiene razón. Lo siento de verdad. ¿Hacemos las paces?

That uses usted grammar.

Lo siento is the standard way to say I’m sorry.

Literally, it comes from sentir (to feel) and means something like I feel it. In modern Spanish, though, learners should treat lo siento as a fixed expression meaning I’m sorry.

The lo does not translate neatly word-for-word in normal English here. It is just part of the expression.

Both can relate to apologising, but they are not always used in exactly the same way.

• Lo siento = I’m sorry
  More clearly expresses regret or remorse.
• Perdón / Perdona = Sorry / Excuse me / Pardon
  Can be lighter, quicker, or used to get attention.

In this sentence, Lo siento de verdad sounds more heartfelt than just Perdón.

De verdad means really, truly, or genuinely.

So:

• Lo siento = I’m sorry
• Lo siento de verdad = I’m really sorry / I truly mean it

It adds sincerity and emotional emphasis.

Yes. Lo siento mucho is very common and means I’m very sorry.

There is a slight nuance:

• Lo siento mucho emphasizes degree: very sorry
• Lo siento de verdad emphasizes sincerity: truly sorry

Sometimes people even combine them:

• Lo siento mucho, de verdad.

Spanish often uses the present tense to make suggestions, especially in questions.

• ¿Hacemos las paces? = Shall we make up? / Do we make peace?
• ¿Vamos a hacer las paces? also works, but it sounds a bit more explicit or literal

The present tense in questions like this is very natural in Spanish, similar to English Shall we…? or How about we…?

In Spanish, the present tense can do more than describe current actions. It can also be used to make:

• suggestions
• offers
• arrangements

So ¿Hacemos las paces? does not literally mean only Do we make peace? in a factual sense. In context, it means:

• Shall we make up?
• Can we make peace?

This is a very common use of the present tense.

Hacer las paces is an idiomatic expression meaning:

• to make peace
• to make up
• to reconcile after an argument

So ¿Hacemos las paces? means the speaker wants to end the conflict and be on good terms again.

It is best learned as a whole phrase.

Because the idiom is fixed as hacer las paces. Spanish uses the plural noun paces in this expression.

You do not normally change it to singular:

• natural: hacer las paces
• unnatural: hacer la paz in this everyday sense

Even though English often says make peace or make up, Spanish uses this plural expression.

Not necessarily. It can be used by both children and adults.

That said, the tone depends on context:

• between adults, it can sound warm, direct, and sincere
• between close friends or partners, it may sound affectionate
• in some situations, it can sound a little soft or emotionally open

It is perfectly normal Spanish, especially when trying to end an argument.

Because only ¿Hacemos las paces? is a question.

Spanish uses both:

• an opening question mark: ¿
• a closing question mark: ?

The first two sentences are statements:

• Tienes razón.
• Lo siento de verdad.

Then the last one is the question:

• ¿Hacemos las paces?

You would usually change the first verb to the usted form:

• Tiene razón. Lo siento de verdad. ¿Hacemos las paces?

Notice that hacemos stays the same, because it means we make / shall we make up?

A very formal conversation might use different wording altogether, but this is the direct grammar change from informal tú.

Yes, it sounds natural in Spain.

All three parts are standard Spanish used in Spain:

• Tienes razón
• Lo siento de verdad
• ¿Hacemos las paces?

Nothing here is especially regional or unusual, so learners can use it safely in Spain.
