I am confused!!! Definitions please

[CCNZ]

I think I have a newfound addiction - knitting and felting bags! So I am googling for free patterns, lol! But I am getting confused - how's a tote different from a bag different from a purse????? Don't know if it's just a cultural thing or maybe I just wasn't taught right, but I always just thought purse is what girls have as opposed to what boys have called wallets, so some of the "purse" patterns are what I'd call bag/handbags.
