Searching for purses on Etsy is a nightmare too. In the UK a purse is what you keep your money in, with a compartment for cards, cash, and change. We don't call them wallets, that's a man's equivelent, and without a compartment for change - because men are less organised, I suppose.
But in the US a purse is a bag. What also doesn't help is Etsy's categories. I wander into purses, it's full of bags, I wander into wallets - it's full of wallets! I struggle to find the inbetween. I wanted to buy a purse for my friend for her birthday and after a -week- of searching I ended up giving up on Etsy and just going to a shop in my local shopping centre. I found a really nice one (funny thing about it, it was a strange pinky beige colour, I wasn't certain if she'd like it - the day I gave it to her she was wearing mostly that colour. I think I got it right.).
It's really difficult sometimes. When I think sweater, I think jumper, no buttons or anything, just...well, a jumper. Cardigans have buttons but in the US I think cardigans aren't always buttoned. It's confusing, but the latter may be down to current fashion.
The differences between diaries and journals gets me too.
