The things you learn: хлеб

So apparently Russian хлеб khleb “bread” is a loanword from Germanic, from a the ancestor of English loaf and German Laib.

I don’t think I would connected those three words off-hand. (Even though the English and German words at least mean the same thing! Perhaps because the word Laib is fairly rare in my speech; I usually talk about ein Brot rather than ein Laib Brot.)
