text: A basic example: the double "O" between "L" and "D" as in "flood" or "blood" as opposed to the double "O" as in "book", "crook", "zoomer", "doomer" or "boomer".
  Russian netizens use word "flood" as "флуд" (transcribes as "flud")
  A harder example: Borscht word (with "sch" + "t" due to borrowing the word from Yiddish (באָרשט), not a Slavic language).
  Overly "official" vocabulary
  The lish may fail to feel neutral to native English speakers, since many words, widely used in Russian in regular talk, can be perceived as official-styled: say, along with "Беречь еду" ("to save food") phrase, Russians would use "Экономить еду" (to "economy" food). However, the "рацион" word in Russian is not similar to English "rations" noun or English "to ration" verb; it is closer to a "diet" noun.
  Different meanings of similar "official-sounding" words
  Such day-to-day use of "officially sounding" borrowed words instead of words native for Russian language is often called out by Russians as "канцелярит" (kan-tsee-lya-rit), basically, language people from offices would "get infected with". Runglishers use word "observe" instead of "follow" regarding adhering to rules sometimes. This is related to a similarity in Russian: "Соблюдай" (Sobludai) word for adhering to rules has the same root as "Наблюдай" (Nabludai), which indeed means observing.
