Lake Peipus dialect (Russian: Причудский говор) is a Russian language variety spoken on both sides of the Lake Peipus in Pskov Oblast, Russia and some counties of Estonia. It originated as a mix of Pskov and Gdov dialects of the Central Russian cluster. As many other dialects from this area, it is often considered to be transitional between Russian and Belarusian. Lake Peipus dialects also include some loanwords from the Estonian language.
