The difference is how words are formed. By the way, Eskimo isn't even a single language. That's like referring to European as a language. Anyway so many Eskimo languages form words by squishing the words together similar to how the Germans do it. In fact they could potentially have fifty words for hot dog, e.g., bighotdog, grosshotdog.
So it would be like if in English we said heavysnow instead of heavy snow. Big whoop right? Anyway so I did a little research and found over fifty words for snow in English. I guess we're just as obsessed with snow as the Eskimoses.
Some are of meteorological origin, some come from winter sport enthusiasts, etc.
