Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'Тираннозавр' in informal contexts where the clipped 'Ти-рекс' (T. rex) is more appropriate for the cultural concept.
- Avoid using 'король' (king) as a direct translation for 'rex' in isolation; it is part of the fixed Latin binomial name.
Common Mistakes
- Incorrect plural: 'T. rex's' (should be 'T. rexes').
- Misspelling as 'T-Rex' or 'T Rex' without the period.
- Using lowercase ('t. rex') in formal scientific writing.
