"Are your T-shirts dirty?"
Translation:¿Tus camisetas están sucias?
Your answer means "you are dirty T-Shirts". Estás means you are.
So you need to specify that the t-shirts are "yours". So either tus camisetas (informal) or sus camisetas (formal or plural) and then you need to ask if they are dirty. Because the t-shirts are third person plural ("they") you need to use "están".
So all together that should be tus camisetas están sucias. I hope I didnt confuse you further and maybe could help you
I believe because there are many camisetas and estan refers to them.
"ustedes" means "you" in the plural form ("you guys", "you all"). "Tu" with an accent means you in the singular, familiar form (like with friends). Tus (without an accent) means "your" referring to a plural-something you have or own. Tus camisetas means "your t-shirts". You couldn't use "ustedes" in this sentence, but you could write "Sus camisetas" to mean the t-shirts belonging to a group of people you're addressing.
Shoshi, can you give me a sentence meaning "are your t-shirts dirty?" that includes the word "ustedes?" The post I was answering was was saying why not "ustedes" instead of "tus", meaning using "you (plural)" instead of "YOUR". It would leave out any possession. I don't see how you can say "you" in a sentence that only uses "your." About "sus camisetas", I meant that if you're speaking to "ustedes" (you plural), you would use "sus camisetas" rather than "tus camisetas." Still "ustedes" wouldn't be in the sentence. Correct me if I'm misunderstanding you.
I didn't mean that you could actually use "ustedes" in the sentence but that the 'you all' can be implied as 'your'. Hence, the use of "sus" would apply to both "usted" and "ustedes", which is, I think, what you're saying as well.
The question that was posted by Andrea seemed more confused than just how it would apply to this sentence. I was trying to expand an explanation beyond just this lesson.
Sorry for the confusion.
You have to use estan rather than son, since "being dirty" is a (usually temporary) state rather than an inherent description/characteristic of the t-shirts.
Additionally, maybe your word order is wrong, but I'm not positive. The re-ordered version "¿Estan sucias sus camisetas?" was accepted for me, at least.
"Tus" is possessive plural, but what's plural is not the possessor (tú). The possessed (camisetas) is what is plural.
Tu camiseta --> your shirt
Tus camisetas --> your shirts
In both, only one person is the owner of your shirts.
For "y'all", you would use ustedes. The possessive pronoun for that is su/sus. (I don't know much about vosotros so I won't risk leading anyone wrong.)
On mobile so not sure how old this question is. Hopefully this helps someone though.
Also, I'm not a native Spanish speaker so if anyone sees any errors in my explanation please correct me!
Spanishdict.com is a very good reference for this but you have to drill down into the definition of Ser and the definition of Estar. Both will have click for conjugations then it will also have a circle with a question mark inside it. Using all this I have finally figured out the "tree" that explains everything not just one part. https://www.spanishdict.com/conjugate/estar
duo's recommended answer: "¿Tus camisetas están sucias?" your answer may have had some other unnoticed error such as sticking an extra S between tus and camisetas
and you should use sus (the usted form) OR tus the (tu` form) not both. they both mean "your," usted form (sus) is formal.
"dirty" is like a temporary condition or a condition as opposed to a characteristic. these are not universal labels, this takes some practice and study. here's another link, part 1 of 4. https://studyspanish.com/grammar/lessons/serest1 in fact,, read that entire grammar guide. Duo is great practice but not a grammar guide
"Es" is the verb form of "ser". It's used for a permanent situation, a physical or character description and personality traits. Think of it as something unchangeable or permanent.
"Esta" is the verb form of "estar". It is used to describe somebody's mood (which can be understood as temporary or changeable), happenings in and around the moment (present tense) and location.
They both mean"to be".
This link is extremely helpful.
It doesn't matter who owns the t-shirts, that is not why "sucias" has to be feminine, it's because "camisetas" is a feminine word, "sucias" is describing the condition of the "camisetas".
Furthermore, because the t-shirts are plural your has to be plural as well, "tus".
