pésimo
/ˈpesimo/ · B2 · adj
lousy, rubbish, abysmal, poor, terrible, awful, rotten, horrible, dismal, appalling, dreadful (very bad)
🗑️ From Latin pessimus = the worst, the same root as pessimist
Latin pessimus is the superlative of malus (bad), so it means the very worst. English kept it in pessimist, someone who expects the worst. A pessimist calls everything pésimo.
