Recently I’ve learned something new in English. I asked the question here, on italki and received an interesting answer. I asked to correct my sentence and how it would sound in a natural way.(this was my version :my tooth was removed… I thought I should have used passive voice and then I found out something new for me I should have said “I had a tooth removed … I have been really thinking for long time, why it lookes like Past Perfect, but has a Passive voice meaning then I asked from AI and it replied that it was a causative sentence.So it means that someone has removed my tooth and it was arranged. If I am not mistaken. And using this construction I can say I had a hair cut, I had my car cleaned.
