Furniture
Note that sofá is masculine: el sofá, never la sofá. This surprises many learners because most Spanish nouns ending in -a are feminine. The word was borrowed from Arabic through French, which explains the gender exception.
Watch out: escritorio and mesa are not interchangeable. A mesa is any general-purpose table, while an escritorio is specifically a work desk, often with drawers. Saying escritorio signals a dedicated workspace, not just any flat surface.
