In an essay on how to pronounce the surname of the Putin's presidential successor Dmitri Medvedev, Serge Schememann writes of English speakers vexed by the Russian language, and gently mocks language teachers who guide them. The author quotes a bilingual journalist from the Moscow Times, who once tutored an American actress how to pronounce the consonants T,D, and N: "the tongue must touch the upper teeth, not the alveolus like in English". Schememann adds, "Russians have their own problems with American names", continuuing, "I never touch the upper teeth with my tongue nor anything that comes up when I google 'alveolus'".
"Alveolus", is a "a small cavity or hollow", and often refers to the pulmonary alveoli (plural) in the lungs, which function during respiration to exchange oxygen and carbon dioxide to and from the blood. Accordingly, the Russian reporter's alarming suggestion -- tongue to alveolus -- might actually constitute a medical emergency. "Alveoli" also refers to other hollows, such as the sockets in which the teeth are rooted.
