monarchy
/ˈmɒnərki/·모나키·noun
rule by a single ruler
GreekCEFR B2
Root
mono- (one) + Greek 'arkhein' (to rule)
Greek monarkhia (rule by one) → Latin monarchia → French monarchie → English monarchy
In a word
mono- (one) + arch (rule) = 'rule by one'. The same arch lives in anarchy (no rule), hierarchy (sacred rule), patriarch (father-rule). "an- (no) + arch" gives anarchy; "hier- (sacred) + arch" gives hierarchy. A single Greek part shaped much of our political vocabulary.
Examples
