If you ignore the relatively recent loanword 'elefanti', the Finnish word for elephant is 'norsu'.
So what? Well, a long time ago, Finns heard (probably from the Swedes) travellers' tales of big thick-skinned animals with majestic tusks living in far-away lands to the south. But they weren't that impressed, because they'd heard of such creatures existing up in the far north, which the Sami called 'morsa' (mursu/norsu in Finnish). When eventually they realised that they weren't in fact the same animal, to avoid confusion mursu came to mean 'walrus', and norsu was used for 'elephant'.
Or so they say.
