Speaking of homophones/homonyms, a whole Finnish tongue-twister family is built around discussions similar to
A: Kokko! Kokoo kokoon koko kokko.
B: Koko kokkoko kokoon?
A: Koko kokko kokoon.
B: "Kokko!" 🙄

roughly

A: Kokko, gather the whole bonfire together.
B: The whole bonfire needs to be gathered?
A: Yes, the whole bonfire needs to be gathered together.
B: "Kokko!" 🙄
where Kokko is the name of B, a hired man.

My fave German words are definitely Weltraum and Schildkröte 💜

@konqrunner @jensclasen Ooh if we're talking compound nouns German IS a top tier competitior, but we've got some doozies, too :D

An oft quoted one is lentokonesuihkuturbiinimoottoriapumekaanikkoaliupseerioppilas (an aeroplane jet turbine motor assistant mechanic, non-commissioned officer in training) but it's almost certainly never seen in-context use. Actual in-use ones are elintarviketurvallisuusvirasto (food safety agency) & pyyhkäisyelektronimikroskooppi (scanning electron microscope).
