"Ich bin es"?
Hello, I've just been speaking to one of the bots on duolingo and it said "Ich bin es" I understand this translates to "it is me" but is there an explanation why? literally this translates to "i am it" but could you not say "es ist ich" ?
No, you can't say Es ist ich.
You could say Das bin ich. but that's slightly different, of course: "That's me." (e.g. when pointing to a picture in a book to say that the person depicted on the photograph is you).
But in a situation such as "Hey Paul, it's me, Linda", German would use Hallo Paul, ich bin's, Linda.
(I don't think I'd use the uncontracted form ich bin es.)
