I have bought a car this year, too.
What does this sentence mean? "Me, too," or "I have done something else and have bought too," or "I have something else and a car too," or "this year too." And how do I emphasize one of these aspects in particular?
In my language, if I want emphasize something, I put "too" directly after it. For example, if my friend bought a car and I want to emphasize that I did too, I might say "I too have bought a car this year." If I put the word too after "bought," it means I did some action and bought too, If I put too after "a car," it means "I bought a house and a car, too," and so on.
