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."
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.
Tengo once.
you are eleven years (old) - tu as onze ans.
i am 41 years old
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.
Once (pronounced OWN-say).
Tengo once años
