The name of Thor's hammer "mjolnir" (as english speakers would see it) did not come through latin though, so the version of the word in germanic languages was inherited independently.

"Mjolnir" means something like "crusher" and the noun "mjol" (flour) means "having been ground up". For example, it can be combined as vetemjöl (wheat flour) or stenmjöl (ground stone or stone powder).
