Frequently Asked Questions

Why is 'sistemas' masculine when it ends in '-as'?

This is a common exception! *Sistemas* is the plural of *sistema*, which is masculine (*el sistema*). This is because the word comes from Ancient Greek, and many nouns adopted from Greek that end in '-ma' (like *tema* or *problema*) are masculine in Spanish, regardless of the '-a' ending.
