Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'оглушать' (to deafen) or 'поражать' (to strike/hit, or to impress). The core is the combination of shock and speechlessness.
- Avoid using for simple 'удивлять' (to surprise). It is much stronger.
Common Mistakes
- Using it for mild surprise (overuse).
- Misspelling as 'dumbfound'* (no extra 'e').
- Confusing it with 'dumb' meaning stupid.
