capacious

The word "capacious" originates from the Latin capax, meaning "spacious" or "able to hold much," which itself is derived from the verb capere, "to take or hold." This core notion of "holding" evolved through Late Latin capaciosus to signify the quality of being able to contain a large amount. The abstract concept entered English in the early 17th century, directly linking the physical act of seizing or containing to the modern sense of ample interior space. Thus, the literal logic of "characterized by a great ability to hold" seamlessly translates to its contemporary meaning of roominess.
