Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'тригон' (trigon), an archaic term for a triangle or a musical instrument. The correct anatomical term in Russian is 'треугольник' (treugol'nik) as in 'мочепузырный треугольник' (mochepuzirnyy treugol'nik).
- The English suffix '-one' should not be associated with the Russian augmentative or chemical suffixes.
Common Mistakes
- Mispronouncing it as /traɪˈɡoʊn/ (stress on the second syllable). Correct stress is on the first syllable.
- Using it as a general synonym for 'triangle' in non-scientific contexts.
- Misspelling as 'trigon' (which is a different, though related, term).
