The “Big List” entry for “heaven” has a minor error: the last sentence of the entry seems to be missing some words.

[Heaven] has cognates in Low German, but the Old High German himil, from which the modern German himmel and the Dutch hemel, the Gothic himins, and the Old Norse himinn are not related.

Thanks. Fixed. I just deleted most of the last paragraph. I don’t recall what I was trying to say, and ultimate answer is that we just don’t know much about the word other than all the cognates having a common Germanic root.
