descuidado
/deskwiˈdado/ · B2 · adj
careless, sloppy, slipshod
🗑️ des- (un-) + cuidado (care) = un-cared-for, neglected or careless
Descuidado splits into des- (not) + cuidado (cared for, from cuidar, to take care). So it describes something left uncared for (neglected) or a person who doesn't take care (careless, sloppy). Compare English careless and uncared-for.
