Quero trabalhar com meu parceiro.

In Portuguese, the subject pronoun is often omitted when the verb already makes the subject clear.

• Quero already means I want
• So Eu quero trabalhar com meu parceiro is correct, but Eu is optional

Including eu can add emphasis, contrast, or clarity, but in a simple sentence it’s usually unnecessary.

Quero is the 1st person singular present tense of the verb querer.

• querer = to want
• quero = I want

A few forms of querer in the present tense:

• eu quero = I want
• você quer = you want
• ele/ela quer = he/she wants
• nós queremos = we want
• eles/elas querem = they want

After quero, Portuguese normally uses the infinitive of the second verb.

So:

• Quero trabalhar = I want to work

This is the same basic pattern as in English:

• I want to work
• Eu quero trabalhar

You do not say Quero trabalho if you mean I want to work, because trabalho is a noun or a conjugated verb form, not the infinitive.

Com means with.

So trabalhar com meu parceiro means to work with my partner.

This is important because Portuguese uses different prepositions depending on the relationship:

• trabalhar com alguém = to work with someone
• trabalhar para alguém/uma empresa = to work for someone/a company

So if you want to say collaboration, com is the right choice.

The possessive and the noun have to agree in gender.

• parceiro is masculine
• so you use meu parceiro

Compare:

• meu parceiro = my male partner
• minha parceira = my female partner

It’s the noun’s gender that controls the form of the possessive.

No. Parceiro can mean several kinds of partner, depending on context.

It can refer to:

• a work partner
• a business partner
• a teammate/collaborator
• sometimes a romantic partner

If the sentence appears in a work context, most people will probably understand parceiro as a professional or collaborative partner. If you specifically mean a romantic partner, context usually makes that clear.

Yes. Com meu parceiro and com o meu parceiro are both possible.

In Brazilian Portuguese, possessives often appear:

• without an article: meu parceiro
• with an article: o meu parceiro

So both of these work:

• Quero trabalhar com meu parceiro
• Quero trabalhar com o meu parceiro

The version without the article is very common and natural. The version with the article can sound a little more specific or can reflect regional/style preferences.

Quero is not automatically rude. It is a normal, direct way to say what you want.

Still, if you want to sound softer or more polite, especially in formal situations, you could say:

• Queria trabalhar com meu parceiro = I wanted / I’d like to work with my partner
• Gostaria de trabalhar com meu parceiro = I would like to work with my partner

So:

• quero = direct and normal
• queria / gostaria de = softer, more polite

A simple Brazilian Portuguese pronunciation guide:

• Quero ≈ KEH-roh
• trabalhar ≈ trah-bah-LYAR or trah-bah-YAR depending on accent
• com ≈ kohng / kohm
• meu ≈ meh-oo said quickly, often closer to myoo
• parceiro ≈ par-SAY-roh

A rough full pronunciation:

KEH-roh trah-bah-LYAR kohm meh-oo par-SAY-roh

A few sound notes:

• lh in trabalhar is a special Portuguese sound, often similar to ly in learner-friendly approximations
• the stressed syllable in trabalhar is the last one: -lhar
• ei in parceiro sounds like ay in say
