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.
