From what I understand that 100 words for snow thing isn't really true, it's just that the language uses compound words like german, so it's just that an adjective + noun is rolled into one word (e.g. powder snow would also be pulverschnee in german, but it's really just the word for powder and snow without the space)
> the language family is generally called Eskimo or Eskimoan, because it includes the Yup'ik languages of Siberia and Alaska as well as the Inuit languages from the northeastern half of Alaska across Canada to Greenland
And I've heard Eskimo is a preferred collective term for North American indigenous arctic dwellers, because Inuit is just one tribe/ethnicity among a few!
But even the concept of what is a "word" in Hungarian is complex. Words have so many different forms depending on the context. As a Hungarian speaker, I perceive three forms of you (te, ön, maga) and one ending that is added to other words to to form a second person form of the word (-d), but even that is a complete oversimplification.
I don't think there is any reason why whale languages would have a concept of discreet words like we have in English.
Fun fact: That is why linguists are more interested in spoken language than written language. Written languages are ultimately "amateur" attempts to codify spoken (natural) languages. Spoken language consists of utterances not letters, words or sentences. Analyzing language requires grouping sounds into compounds that serve specific functions or carry specific semantics but for spoken language the structure will be a lot fuzzier and more complex than for the simplified written language even if the author attempts to replicate spoken language in writing. Even phonemes don't tell the full story.
