asunto
ES [aˈsunto] · FI [ˈɑsunto] · same spelling, unrelated worlds
To immerse myself in the target language (here Spanish), I decided to employ a sneaky trick I used to learn English when I was young - play games in the target language.
One of the games I’ve switched to Spanish is League of Legends, a quite popular multiplayer game. Before every game, each player first needs to select a champion which they do not want to play against, and then they need to select a champion that they want to play as. Once either the ban or the pick is confirmed, the banned and selected character throw in a predefined voiceline.
Aiming to play as a champion that goes by the name “Yone”, it seemed reasonable to ban a champion that is very difficult to play against as Yone - LeBlanc. Banning LeBlanc triggers the sentence of interest.
“Tengo asuntos más importantes que atender.”
Banned LeBlanc is trying to keep it cool, as if she did not even want to play the game. Anyways, the interesting part is that in Spanish, asunto is a word for “matter”, “an affair”, “a piece of business”, but in Finnish, asunto means an apartment. My initial thought was “Why the hell is LeBlanc mixing Finnish with Spanish?”, until I of course checked with a translator.
Unfortunately, there is no shared root to catch you. Spanish asunto is Romance, from Latin assumptus. Finnish asunto is Finno-Ugric, built from asua, “to live / reside.” Two languages, one identical word, zero relation.
As far as I can tell this is pure coincidence rather than a shared root — the same string just happening to land in two unrelated families. Apparently that's the stickiest kind of false friend: no etymological warning bell, just two confident definitions fighting over identical letters.
