Frequently Asked Questions
How do I know whether to use 'serios' or 'serias'?
You need to look at the group of people or things you are describing. If the group is all female (like 'las abuelas'), use 'serias.' If the group is all male (like 'los hombres') or a mixed group (like 'los profesores y las alumnas'), use the masculine form 'serios.'
Is 'serios' used to describe a temporary state or a permanent personality trait?
'Serios' usually describes a fundamental quality or personality trait, so it almost always uses the verb 'ser' (to be, permanent): 'Ellos son serios' (They are serious people). If someone is temporarily looking serious, you might use 'estar' (to be, temporary) with a different adjective, but 'serios' is strongly associated with 'ser'.
