"Do you have a brother?"

Translation: ¿Tú tienes un hermano?

[PureBrainMeat]

Difference between "Tengo" and "Tienes"?

[psluk]

In Spanish, you have to agree the verb form depending on what/who is performing the action:

Comer (to eat): yo como, tú comes…

Here's a guide on that: https://forum.duolingo.com/comment/24939344

Tener (to have) is an irregular verb (not only does the ending change, but the root does too): yo tengo, tú tienes…

Here's a guide on tener: https://forum.duolingo.com/comment/24214951

[RobbieMill20]

why is it tienes and not tiene as were saying have and not haves?

[AndrewnotinJapan]

You can use 'tiene' as long as you use 'usted' as well to make it a formal question, e.g. ¿Tiene Ud. un hermano? 'Usted' usually shortens to 'Ud.' (with capital letter and full stop) in written Spanish.

[ZolKel]

Verbs in second person singular ends with "s" in Spanish.

[ironman123121]

Thanks for good info! Zolkel

[ZolKel]

Why not "¿Tienes tú un hermano?" is promoted as answer? Is not it the one that is grammatically correct? It is accepted anyway.

[ana.ofelia]

You could say it, but it sounds more natural ¿Tú tienes un hermano?, or even more natural ¿Tienes un hermano?

[WinterAnge8]

I said,¿Tu tienes un hermano?, but i counted it wrong. Why

[Glenn390416]

Likely because of the incorrect spelling of Tú.
Tu →Your
Tú → You

[Jared222788]

This was my question, thank you VERY much!

[jefry815489]

WinterAnge8 you must write "tú" when it's a subject.
"Tú comes comida"= You eat food.

Tu is a possessive adjetive "your"
Tu carro rojo es bonito=your red car is beautiful

[karenlindq]

When is Tu used with an accent (tú) versus without? What is the rule for that?

[psluk]

One-syllable words usually don't have an accent mark. However, there are some groups of words that may have, or not, an accent mark depending on their meaning, which are:

Stressed form	Meaning	Unstressed form	Meaning
tú	you [pronoun]	tu	your [possessive adj.]
él	he, him [pronoun]	el	the [article]
mí	me [pronoun]	mi	my [possessive adj.] mi, E [musical note]
sí	yes [adverb]	si	if, whether [conjunction] B, ti [musical note]
té	tea [beverage]	te	(to) you [pronoun] tee [letter]
dé [from dar]	give [verb]	de	of, from [preposition] dee [letter]
sé¹ [from saber] sé² [from ser]	¹I know ²(you) be! [verb]	se	(to) itself [reflexive pronoun]
más	more [adjective/adverb]	mas	but [conjunction]

[karenlindq]

Thank you! I haven't learned the basic rules and feel like lazy cow for posting rather than looking it up.
But, muchas gracias for posting that.

When to use tienes or tengo?

[psluk]

In Spanish, you have to agree verbs (actions) with the subject, just like I am, you are, he is in English.

https://forum.duolingo.com/comment/24939344

Tener is irregular, so it does not follow the regular conjugation pattern.

Subject	Conjugated form
yo	tengo
tú	tienes
él, ella, usted	tiene
nosotros, nosotras	tenemos
ellos, ellas, ustedes	tienen

https://forum.duolingo.com/comment/24214951

[Skylar770660]

Why 'tienes' instead of 'tengo'? I think it's a matter of grammar . . . .

[Thttallrarechick]

Why do they list 'verdad' for 'Do you' if its incorrent?

[msmax43]

Tienes not tengo? Explain por favor.

[Jim8161]

tienes = you have
tengo = I have

[jAsMiNe52_]

My mistakes are because of me writing fast

[msmax43]

So much to remember!

No - look at the answer Duo provided and you can see that "brother" is "hermano"
