spaciousness

The word 'spaciousness' is built upon the Latin root spatium, which originally denoted an expanse, a distance, or an interval. The suffix -ious (from Latin -osus) was attached to form the adjective 'spacious,' meaning "full of space." Finally, the Old English abstract noun-forming suffix -ness was added, a common Germanic pattern for deriving qualities from adjectives. Thus, the word's logical construction moves from the concrete concept of an area (spatium) to the descriptive quality of being roomy (spacious), and finally to the abstract state or attribute of that quality (spaciousness).
