Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like *'само-удерживание'*. The correct conceptual equivalent is 'самодостаточность' (self-sufficiency).
- Do not confuse with 'сдержанность' (restraint), which relates more to behavior than to systemic independence.
Common Mistakes
- Misspelling as *'selfcontainment'* (hyphen is standard).
- Confusing with 'self-control' (which is about managing impulses, not systemic independence).
- Using it as a countable noun (e.g., 'a self-containment' is incorrect).
