sentance usage

Question

Can you use both example for the same meaning?

Ella es enferma hoy.

Esta enferma hoy.

Thanks

Answer 1

No,

As I understand, these two sentences have completely different meanings.

1. Ella es enferma hoy. You used "ser" here, which is for defining characteristics. So, you said "She is sickly today." This really makes no sense, but without "hoy", you get "She is sickly."
2. Esta enferma hoy. You used "estar" here. Estar is basically for temporary things, so you basically said "She is sick today."

I think you meant the second sentence!

I hope this helps.

Answer 2

No, ser and estar have different uses. Ser is for traits or characteristics generally and estar is for states of being that can change, so which do you think is correct?
