Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'проект' (project as in plan/venture). 'Projection' is 'проекция' (math/psychology) or 'прогноз' (forecast). 'Проекция' in Russian is narrower, primarily geometric/psychological.
Common Mistakes
- Using 'projection' to mean 'a major plan or enterprise' (that's 'project').
- Confusing 'projection' (act/result) with 'to project' (the verb).
- Misspelling as 'progection'.
