In the new Czechoslovakia the village was written Moravany from 1920, and in 1927 the river was added to it: Moravany nad Váhom, Moravany on the Váh, to tell it apart from the other Moravanys in the country. Small as that looks, it is exactly what a modern state does — it makes every place unambiguous, because railways, post offices and land registries cannot work with three villages of the same name. Next door, Piešťany was booming as an international spa, and Moravany began doing what it still does: sending people down the hill to work.V novom Československu sa obec od roku 1920 písala ako Moravany a v roku 1927 k menu pribudla rieka: Moravany nad Váhom — aby sa dali odlíšiť od ostatných Moravian v krajine. Vyzerá to ako maličkosť, ale presne toto moderný štát robí: zbavuje miesta nejednoznačnosti, lebo železnica, pošta ani pozemková kniha si s tromi rovnako pomenovanými dedinami neporadia. Vedľa, v Piešťanoch, vtedy prekvitali medzinárodné kúpele, a Moravany začali robiť to, čo robia dodnes: posielať ľudí dolu do mesta za prácou.
