Do you change the word idiot to suit the gender of the person or is it always idiota? Does idioto not exist?
We use idiota regardless of the gender of the person. The word idioto does not exist.
You do, however, use the gender-relevant article. So um idiota for a male idiot and uma idiota for the female variety.
This does feel a bit counter intuitive, given that so many other people-related words do follow gender. Guess it’s “just one of those things”…
Edit: I came across a similar word this morning. Taxista (taxi driver) ends in ‘a’ regardless of whether it’s a taxista or o taxista. Same with motorista (driver).
Perfectly explained, @Tomas
