|1.||n denoting 10--9: nanosecond|
|2.||indicating extreme smallness: nanoplankton|
|[from Latin nānus dwarf, from Greek nanos]|
Extremely small: nanoid.
One-billionth (10-9): nanometer.
nano-pref. [SI: the next quantifier below micro-; meaning * 10^(-9)] Smaller than micro-, and used in the same rather loose and connotative way. Thus, one has nanotechnology (coined by hacker K. Eric Drexler) by analogy with `microtechnology'; and a few machine architectures have a `nanocode' level below `microcode'. Tom Duff at Bell Labs has also pointed out that "Pi seconds is a nanocentury". See also quantifiers, pico-, nanoacre, nanobot, nanocomputer, nanofortnight.
