word-forming element meaning "new, young, recent," used in a seemingly endless number of adjectives and nouns, mostly coined since c. 1880, from Greek neos "new, young, youthful; fresh, strange; lately, just now," from PIE root *newo- (see new). In the physical sciences, caeno-, ceno- is used in the same sense. Paleo- is opposed to both.
word-forming element forming nouns meaning "rule or government by," from French -cratie or directly from Medieval Latin -cratia, from Greek -kratia "power, might; rule, sway; power over; a power, authority," from kratos "strength," from PIE *kre-tes- "power, strength," suffixed form of root *kar- "hard." The connective -o- has come to be viewed as part of it. Productive in English from c. 1800.
