Capacious is an adjective that means roomy or having a lot of space.
Capacious comes from the Latin word capax (cap AXE) which roughly translates to ‘capacity.’ It may help to think of a large room as having a capacity to hold many people or things, so a capacious room would be a room with lots of space.
I love the capacious kitchen in my new apartment. It’s so nice to have enough space for everything I need to cook.
