She is a teacher or she does teaching

[Rachel Adams]

Is it wrong to say "Her sister does teaching"? Instead of saying "she is a teacher."

Is it wrong to say "Her sister does teaching" no question mark here instead of [strike]saying[/strike] "She is a teacher"?

Yes, that's wrong. You could say "She teaches" but that's not as natural as "She is a teacher".

Please note my corrections above.

We say things like "She teaches mathematics" or "She teaches third grade" or "She teaches high school physics".

 

[Skrej]

You could say something like "She does some teaching on the side" or "She does some teaching now and then", but that's different from calling her a teacher.

Put question marks at the ends of sentences, not in the middle.

When you're quoting a complete sentence, capitalize the first letter of the quotation.
