text: A/E letters and D/T letters can be confusing for a Russian. The "T" sound in English sounds softer, compared to the Russian way to say "T"; while it's the other way round for "D". Therefore, "d" and "t" may be confused in Runglish. In fact, words like "card" and "standard" can be found in Russian "карта" and "стандарт".
  The [ Æ ] diphthong (as in "bad" or "bat") can be a problem. While Russian language has "Я" letter with its sound, close to "æ"; the letter is almost never used to transcribe that sound. Russians transliterate "and" the same way they transliterate "end": "Энд".
  Instead most words with "-ia", are transliterated as "-ия". Older example: malaria and малярия, recent example: Costa Concordia was immediately transliterated as Коста Конкордия.
  There is no strict "A with [Æ] sound in English word" gives "Э" with "eh" in the resulting word" rule, though. In some words (e.g. "caliber"/"calorie"/"bar"/"plastic"/"card"/"standard"/"bank"), Russian language replaces the "Æ"-like sounds with "cyrillic А" letter and "ɐ" sound.
  Only the English words that end with "-ar" or "-arity", are introduced into Russian with "-яр" or "-ярность" respectively. This goes to the words like "singularity" and "polarity", which can be found in Russian as "сингулярность" and "полярность" respectively.
