Word Origin & History
O.E. hundred "a counting of 100," from W.Gmc. *khundrath (cf. O.N. hundrað, Ger. hundert), first element is P.Gmc. *hunda- "hundred" (cf. Goth. hund, O.H.G. hunt), from PIE *kmtom "hundred" (cf. Skt. satam, Avestan satem, Gk. hekaton, L. centum, Lith. simtas, O.Ir. cet, Bret. kant "hundred"). Second
element is P.Gmc. *rath "reckoning, number" (cf. Goth. raþjo "a reckoning, account, number," garaþjan "to count"). O.E. also used simple hund, as well as hund-teontig. Meaning "division of a county or shire with its own court" (still in some British place names and U.S. state of Delaware) was in O.E. and probably represents 100 hides of land. The Hundred Years War (which ran intermittently from 1337 to 1453) was first so called in 1874.
