False friend ES looks like EN
divertido
ES [diβeɾˈtiðo] · looks like English “diversion / divert”
Brain assumed a diversion - a detour, a distraction Actually fun · funny · entertaining
Divertido begs to be read as English diverted - something that’s been pulled off course. It actually means fun. Una película divertida is a funny, entertaining movie, not one that has been distracted.
Why it happens
As far as I can tell, a faux ami from semantic drift - a shared root whose meanings wandered apart. Apparently both go back to Latin divertere (“to turn away”). These fool you precisely because the resemblance is real: your instinct isn't wrong to feel the connection, only wrong about where it went.
