Variations and inflections

I was just reflecting today, having run into a little old Italian lady at work, how many ways there are to say in Italian that you agree with someone (such as in English, if someone says something you agree with, you might reply by saying "exactly"). E vero, giusto, esatto, ecco, claro, a punto, or even just by saying "eh" in a particular tone of voice. So this now has me counting up in my head how many different ways we say it in English...true, exactly, definitely, yes, indeed, you're right, mmm-hmm, etc.
