Common Pitfalls
Translation Traps (for Russian speakers)
- Прямого устойчивого эквивалента нет. Не путать с более распространёнными 'агути' (agouti) или 'дикобраз' (porcupine). Корректный перевод — 'акучи' (транслитерация) или 'южноамериканский горбатый грызун' (описательно).
Common Mistakes
- Misspelling as 'accouchi', 'acouchy', or 'akouchi'.
- Mispronouncing with /aʊ/ (as in 'couch') instead of /uː/.
- Using it as a general term for any large tropical rodent.
