英文词源
- bacterium
- bacterium: [19] Bacterium was coined in the 1840s from Greek baktérion, a diminutive of báktron ‘stick’, on the basis that the originally discovered bacteria were rod-shaped. At first it was sometimes anglicized to bactery, but the Latin form has prevailed. Related, but a later introduction, is bacillus [19]: this is a diminutive of Latin baculum ‘stick’, and the term was again inspired by the microorganism’s shape. Latin baculum is also responsible, via Italian bacchio and its diminutive form bacchetta, for the long French loaf, the baguette.
=> bacillus, baguette, débacle, imbecile - bacterium (n.)
- c. 1848, singular of bacteria (q.v.).
