sniðum

Could you clarify what "sniðum" refers to? For example, is it a word or form in a particular language (such as Icelandic), a place or surname, or something else? Do you want a general dictionary-style entry about the term itself, or a focused article on a specific subject named "Sniðum"? Once I have the context, I can generate a concise, neutral wiki-style article under 300 words.
