Learn Spanish (Spain): El señor tiene sesenta años. - The gentleman is sixty years old.

It helps to look at the letter 's'. Sesenta has an 's' in the middle, just like the word seis (six). The word for 70 is setenta, which has a 't' in the middle, similar to siete (seven).

Why does the sentence use tiene (has) instead of the Spanish word for "is"?

In Spanish, you do not say that you are a certain number of years old. Instead, you say that you have years. So this sentence literally translates to "The gentleman has sixty years." You will always use the verb tener (to have) when talking about age.

Is the little line over the 'n' in años important?

Very important! It completely changes the meaning of the word. The letter ñ sounds like the "ny" in the English word "canyon". If you use a regular n, the word becomes anos, which means "anuses". Always remember the ñ when talking about age so you do not accidentally say the gentleman has sixty of them!

I usually see señor translated as "Mr.". Can it also mean "gentleman"?

Yes! When used directly with a last name, like el señor García, it translates to "Mr. Garcia". But when used on its own to describe a person like in this sentence, it translates to "gentleman" or simply "older man".
