Eureka Classis
On June 7, 1911, seven ministers and sixteen congregations organized to form the Eureka Classis. The name of the Classis came from the Greek word ‘eureka’ which means ‘I found it’ and not on the town Eureka, South Dakota, where the second meeting of the Classis would be held. The name was designed to mean that they had found a solution to their doctrinal problems with the rest of the denomination.
Tachanka
There are at least two plausible hypotheses about origin of the word "tachanka". The etymological dictionary of Vasmer suggests that the word derives from Ukrainian "netychanka" ("нетичанка"), Polish "najtyczanka", a type of a carriage named after the town of Neutitschein, now Nový Jičín in the Czech Republic. According to another opinion, it is a Ukrainian diminutive, or endearing form of the word "tachka" (, meaning 'wheelbarrow'). Still another opinion is that it is a contracted word 'tavrichanka' for rugged carriages known in Southern Ukraine and Crimea, derived from the name "Taurida" for this area. However the latter derivation is dubious because the 'tavrichanka', a large, rugged agricultural carriage, is of completely different design.
