I'm revising my English language knowledge. I thought why not to start by basics. And at this moment I'm at Parts of a Sentence.
In given statement:
They are washing the dishes.
"They" is a simple subject, "are washing" compound predicate "the dishes" dependent clause
Is that correct? If not, please explain which element is described wrongly. Is there any tool that can analyze my sentences and give me hints what are respective elements?
