Words derived from the same source as 'Loft' seem to universally mean 'sky' or 'air' in almost all germanic languages... except English where it means 'small room near the ceiling'.
I guess Wiktionary might be mistaken, but it says the not-really-so-modern meaning of ‘loft’ is shared among Germanic languages: https://en.wiktionary.org/wiki/loft
Well, the word apparently has a bit unusual etymology:
> The word has been used as a euphemism for "poison" since Old High German, influenced by Late Latin dosis (“dose”), from Ancient Greek δόσις (dósis, “something given; dose of medicine”). The original meaning "gift" has disappeared in contemporary Standard German.
So yeah, the word is the same, it just became divorced from the former meaning.
oh wow i was actually completely unaware of the etymological history of it, but after reading what you said i did some research and confirmed it for myself. thank you for sharing that with me, and for allowing me to turn an unknown unknown into a more productive form :^)
