"My sister is not like this."

Translation: Mia sorella non è così.

My answer is "Mia sorella non è come questo." It is right, isn't it? grammatically.

That's what I tried and it was wrong.

I tried that too, but instead of "questo" I write "questa".

Can we also say " Mia sorella non è come cosi" ?

[Juni8]

why is saying "LA mia sorella..." not correct??

[Jose.Cazares]

When speaking of family, as long as the word is unmodified you can omit the article. So, you can say "mio fratello" but not "miei fratelli". (It would be "i miei fratelli")

[Juni8]

ohh I see.. Thank you!!

[Pocahontasymulan]

You "must" omit the article.
