bacteria
/bækˈtɪəriə/Microscopic single-celled organisms, sometimes causing disease
From Greek, transmitted through New Latin bacteri (Little rod).
from New Latin bacteria, plural of bactērium

In 1838, German naturalist Christian Gottfried Ehrenberg gave these tiny organisms a name built from Greek baktḗrion, “little rod.” That was not poetic guesswork: the first bacteria scientists observed looked like microscopic sticks, so the name was essentially a pocket-sized description. The word traveled through New Latin, where bacteria became the plural of bacterium; strictly speaking, using bacteria as a singular is a grammatical slip, though it is common enough to be understood. The same rod image survives in words such as bacteriology, while cousins like aerobic—coined by Louis Pasteur in 1863—describe organisms that live with oxygen. Next time you hear bacteria, picture not a sinister germ but an invisible forest of little rods inhabiting soil, boiling springs, deep rock, and your own hands.
