用法筆記

Spher- functions as a bound combining element rather than an independent word. It attaches to Greek and Latin roots, often with a linking vowel -o- or directly to another stem. The most common forms derived from it are sphere (noun), spherical (adjective), and spheroid (noun/adjective). Many scientific terms (atmosphere, biosphere, stratosphere, hemisphere) are formed by pairing spher- with a prefix or another root that describes what the sphere contains or represents.
