nano-
introduced 1947 (at 14th conference of the Union Internationale de Chimie) as a prefix for units of one thousand-millionth part, from Greek nanos "a dwarf." According to Watkins, this is originally "little old man," from nannos "uncle," masc. of nanna "aunt" (see nana). Earlier it was used as a prefix to mean "dwarf, dwarfish," and still in a non-scientific sense of "very small."
ORIGIN: from Greek nanos , Latin nanus dwarf: see -o- .
nano-
combining form.
a billionth (used in subminiature units of measurement): Nanosecond = a billionth of a second.
very small; dwarf: Nanoplankton = a very small plankton.
