Describing People
Mistake: “Calling a person `simple` can sometimes be misunderstood.”
Correction: While `una persona simple` can mean 'a humble, down-to-earth person', it can also sometimes mean 'a simple-minded person'. The word `sencillo/a` is often a safer and more positive choice to describe a person's personality as 'simple' or 'unpretentious'.
