kaiser

"an emperor," O.E. casere, obscure after M.E., but revived 1858 in ref. to the Ger. emperors of Austria and, after 1870, Germany, from Ger. Kaiser, from Bavarian and Austrian spelling of M.H.G. keisar, from O.H.G. keisar "emperor," an early borrowing of L. cognomen C?sar (q.v.). The Gmc. and Slavic peoples seem to have called all Roman emperors "caesar" (cf. O.E. casere, O.N. keisari). Said to be the earliest L. loan word in Gmc.

kakistocracy

1829, "government by the worst element of a society," coined on analogy of aristocracy from Gk. kakistos "worst," superl. of kakos "bad" (which is perhaps related to the general IE word for "defecate") + -kratia "rule of," from kratos "strength, power, rule" (see -cracy).
