No quiero pelear.

In Spanish, no usually goes right before the conjugated verb.

So:

• No quiero pelear = I do not want to fight
• Quiero no pelear is possible in some contexts, but it means something more like I want not to fight or I want to avoid fighting, with extra emphasis on the second action.

For a normal, natural I don't want to fight, No quiero pelear is the standard wording.

Spanish often leaves out subject pronouns when they are not needed, because the verb ending already shows who is doing the action.

• quiero = I want

So No quiero pelear already clearly means I don't want to fight.

You could say:

• Yo no quiero pelear

but yo is usually only added for emphasis, contrast, or clarity.

Quiero is the present tense of querer.

It is the first person singular form:

• yo quiero = I want

So the sentence is in the present:

• No quiero pelear = I don't want to fight

After verbs like querer (to want), Spanish usually uses an infinitive for the second verb.

Pattern:

• querer + infinitive

Examples:

• Quiero comer = I want to eat
• Quiero salir = I want to go out
• No quiero pelear = I don't want to fight

So pelear stays in the infinitive because it is the action being wanted or not wanted.

Because Spanish does not use a separate word like English to before the infinitive in this structure.

In English:

• want to fight

In Spanish:

• querer pelear

The infinitive itself already does the job:

• pelear = to fight / fighting depending on the structure

So No quiero pelear is the correct equivalent of I don't want to fight.

No. Querer is an irregular verb.

Its stem changes:

• e → ie in most present-tense forms

Examples:

• yo quiero
• tú quieres
• él/ella quiere

But:

• nosotros queremos
• vosotros queréis

So quiero is something you need to learn as an irregular form.

Yes, pelear is basically a regular -ar verb in its endings.

Its infinitive is pelear = to fight / to argue

Some forms:

• yo peleo
• tú peleas
• él pelea

The sentence uses the infinitive form, so you do not see any conjugation here:

• No quiero pelear

Pelear can mean both:

• to fight physically
• to argue / quarrel

The exact meaning depends on context.

So No quiero pelear can mean:

• I don't want to fight
• I don't want to argue

If you want to be more specific:

• No quiero discutir = I don't want to argue
• No quiero luchar = I don't want to fight/struggle (less like a personal quarrel, more like combat/struggle depending on context)

Good question. Both are related, but they are not exactly the same.

• pelear = to fight / to argue
• pelearse = to fight with each other / to fall out / to have a quarrel

Examples:

• No quiero pelear = I don't want to fight / argue
• No quiero pelearme contigo = I don't want to fight with you

So if you want to make the idea of fighting with someone more explicit, pelearse con alguien is very common.

Yes, but it changes the meaning slightly.

• No quiero pelear = general: I don't want to fight / argue
• No quiero pelearme = more like I don't want to get into a fight / I don't want us to fall out

Often, pelearse is followed by con:

• No quiero pelearme contigo = I don't want to argue with you

Without context, No quiero pelear is broader and simpler.

Spanish and English build negation differently.

In Spanish, a single no before the conjugated verb is enough:

• No quiero = I don't want

You do not need an extra word equivalent to do.

English uses:

• I do not want

Spanish uses:

• No quiero

So the negative system is simpler here.

A rough pronunciation in Spain is:

• No quiero pelear
• approximately: noh KYEH-roh peh-leh-AR

A few helpful notes:

• quie- in quiero sounds like kyeh
• r in quiero is a light tap
• pelear has the stress on the last syllable: pe-le-AR

In much of Spain, ll in pelear is usually pronounced like a y sound.

Not exactly.

• pelear often suggests fighting with someone or arguing
• luchar usually means to struggle / to battle / to fight in a broader sense

Compare:

• No quiero pelear = I don't want to fight/argue
• No quiero luchar = I don't want to struggle / battle

If you are talking about an argument or quarrel, pelear is usually the better choice.

Yes. No quiero pelear is natural and not rude by itself.

Its tone depends on how you say it and the context. It can sound:

• calm and peaceful
• emotional
• firm

If you want to sound softer, you could say:

• No quiero discutir
• No quiero problemas
• Prefiero que hablemos tranquilos = I'd prefer us to speak calmly

But No quiero pelear is a perfectly normal sentence.

Spanish word order is flexible, but the normal neutral order is:

• No quiero pelear

Other orders may sound marked, poetic, or emphatic:

• Quiero no pelear = emphasizes the idea of not fighting
• Pelear no quiero = unusual in ordinary conversation; sounds strongly emphatic or stylized

For everyday speech, stick with:

• No quiero pelear

You would change the form of querer:

• No quieres pelear = You don't want to fight informal singular
• No quiere pelear = He/She doesn't want to fight or You don't want to fight formal singular
• No queréis pelear = You all don't want to fight in Spain
• No quieren pelear = They don't want to fight or You all don't want to fight in Latin America/formal plural

So the structure stays the same:

• No + querer (conjugated) + infinitive
