Correction to English

Question

Excellent topic.  Just a small thing:  the word "family" is singular in English, as in "Your family is cool."

Answer

Hola Marcos,
After consulting this with our English native team, it seems that the collective noun "family" in English can take both singular and plural, depending on the context, with the British English generally favouring the plural and the American English favouring the singular. Here is a link with some information. 
Gracias y saludos,

Answer

There is also an error in one of the English translations. I apologize, I keep forgetting to report it after I see it on a test, but it involves family and I think it says "want" instead of "wants" or some some similar verb.
