Yestonians

Yestonians ( , singular: ; ) was a derogatory epithet for historically ethnic Estonians brought from Russia to Estonia after World War II to staff the political structures of Soviet Estonia with cadres loyal to Moscow. While their ethnicity was Estonian by descent, they grew up in the Russian/Soviet environment, which meant that for many, the primary language was Russian (the ethnic Estonian language was a second language), which made them prone to apply Russian-language pronunciation rules in their Estonian-language speech.
