Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'frill' as just 'оборка' (flounce/ruffle on clothing). The more accurate zoological term is 'кожная складка' (skin fold) or 'воротник' (collar). The compound adjective 'frill-necked' is best rendered as 'с воротником на шее' or 'ошейниковый'.
Common Mistakes
- Misspelling as 'frill-neck lizard' (less common but acceptable) or 'frilled-neck lizard'. Confusing it with other 'dragon' lizards. Using 'frill' as a verb for the lizard ('it frills') is non-standard; use 'raises its frill'.
