divertido
ES [diβeɾˈtiðo] · looks like English “diversion / divert”
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.
And here both words are telling the truth about the same ancestor. Both descend from Latin divertere, “to turn away.” English kept the literal sense — turn aside, detour, distraction → divert. Spanish turned the mind away from its troubles instead — amuse, entertain → divertido. Same root, two destinations. English even keeps a ghost of the Spanish meaning in the near-archaic “a diverting tale.”
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.
