Ella tiene 11 (ohn-say) años.
However if you want to say I am eleven years old you would say J'ai onze ans.
Oh, dude, it's like super easy. To say "I am 11 years old" in Spanish, you just say "Tengo once años." That's it. Like, no big deal. Now you can impress all your Spanish-speaking friends with your newfound knowledge.
我今年十一歲 Wǒ jīn nián shí yī suì (I am eleven years old this year)
Eleven in Spanish is "once," pronounced "ohn-say."
Yes, you should use hyphens in "eleven-year-old" when it functions as a compound adjective before a noun. For example, you would say "an eleven-year-old child." However, when using it as a predicate adjective after a verb, you do not need hyphens: "The child is eleven years old."
The expression to say how old you are or a material object is in Spanish is "tener ____ años".If you literally want to translate "years old" into Spanish, this would be "años de vejez", but this is nonsense to any Spanish speaker.
you are eleven years (old) - tu as onze ans.
Tengo once.
You could say "Tengo once años". (Pronounced TEHN-goh OHN-say AHN-yohs). Literally this means "I have eleven years", but is translated as "I am eleven years old". Or...you could say "Soy de once años de edad". (Pronounced SOY DEH OHN-say AHN-yohs DEH ee-DAHD). Literally "I am of 11 years of age". It carries the same translation as above.
Yo tengo once años. This translates to "I have eleven years". This is how people who speak Spanish say their age. If you wanted to say "You are eleven years old" you would say: Tú tienes once años.
i am 41 years old
Once (pronounced OWN-say).
