One word that gets used a lot more in Russian than in English is киоск kiosk. I think the average American doesn't normally use this word, and I think most of us don't even have a clear idea of what it means. My first encounter with the word in English was at the University of Arizona. There were several brick structures which we called kiosks that had bulletin boards attached to which one could staple announcements for concerts, parties, businesses, etc. That is not what киоск means in Russian. A киоск is a small stand or booth where people sell things. Usually it's a free-standing structure, though it can also be part of a larger one. (It's never just a cart.) These are everywhere in Russia: at train stations, in the subway, anywhere there is a pedestrian street. And they sell all kinds of stuff. To say what kind of stand it is, Russians sometimes put an adjective before the noun:

Sometimes the description of the stand comes in the genitive case after the noun:

During the Soviet period you could find the oddest things at kiosks. The ones that seemed to have the most variety were the газетные киоски. I remember seeing toothbrushes and red pepper being sold в газетных киосках.

The noun itself is fairly straightforward with no grammatical quirks (as long as you remember the seven-letter spelling rule). Here are some sample sentences:

Here are some shots of various kiosks around Kazan. This first one is basically a beer, snacks, and tobacco place. Its sign reads:

There is a reason that they offer printing services here. Right nearby there is an Architectural University. Universities here don't offer printing services to their students. They often don't have the internet. And students are too poor generally to own printers.

This next one is a flower stand.

And here we have a souvenir stand:

This next one is a shoe repair stand.

And here is a beer stand. The beer stand is interesting because you have to pay for both the beer and the container. If you bring your own plastic bottle in, then you just pay for the beer and they fill your bottle for you.

Last but not least, here is a little auto supply kiosk. They mostly sell oil and antifreeze.
