Переклад:It is her!
Видання The Cambridge Grammar Of The English Language (April 15, 2002), Pullum & Huddleston (досить авторитетне) підсумувало це правило коротко і по-британському:
"Myth: Expressions like "It was me" and "She was taller than him" are incorrect; the correct forms are "It was I" and "She was taller than he."
Pullum responds: The forms with nominative pronouns sound ridiculously stuffy today. In present-day English, the copular verb takes accusative pronoun complements and so does "than." My advice would be this: If someone knocks at your door, and you say "Who's there?" and what you hear in response is "It is I," don't let them in. It's no one you want to know."
