This name was created by Communist parents who were eager to reject traditional names.
When spelled as Револт, it is a combination of the Russian noun революция
(revolyutsiya) meaning "revolution" with the surnames of Ленин
(Lenin) and Троцкий
(Trotskiy), which refer to the Soviet politicians Vladimir Lenin (1870-1924) and Leon Trotskiy (1879-1940).
But when spelled as Револьт, it is derived from either the English noun
revolt (see the other entry for
Revolt), the French word
révolté meaning "rebel" as well as "rebellious" or from the Russian noun револьвер
(revolver) meaning "revolver" (as in, the handgun).
A known bearer of this name was Revolt Pimenov (1931-1990), a Russian historian, mathematician and human rights activist.
