Soviet

The word "soviet" entered English directly from Russian "совет" (sovét), which means "council," "advice," or "assembly." The Russian term itself originates from the Old Slavic root sŭvětŭ, a compound of sŭ- ("with," "together") and větŭ ("word," "counsel"), thus conveying the sense of "a coming together for discussion." This ancient root is cognate with the English word "wit," both deriving from the Proto-Indo-European weid- ("to see, to know"). In the early 20th century, "soviet" was adopted into English to specifically denote the revolutionary workers' councils in Russia, and later became the definitive term for the political system and state of the Union of Soviet Socialist Republics (USSR).

This word is a direct borrowing from Russian and functions as a single, unanalyzable unit in English. Its internal structure is not composed of productive English morphemes.
