    The Art of Holding More

    Capacious is the thinking person’s alternative to big. While a mountain is big, a cathedral or a cargo ship is capacious. The word implies a void waiting to be filled, suggesting an interior that exceeds expectations. It is a term of utility as much as scale.

    The word fills a specific linguistic gap by bridging the physical and the intellectual. You can have a capacious handbag that defies the laws of physics, but you can also possess a capacious memory. In both instances, the focus is on the ability to receive and retain. It suggests an openness that smaller, narrower things lack.
