Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid directly translating 'oscillation' as 'колебание' when referring to simple hesitation or doubt; 'vacillation' or 'hesitation' might be more natural. In technical contexts, 'колебание' is correct.
Common Mistakes
- Confusing 'oscillation' (regular, repetitive) with 'fluctuation' (can be irregular).
- Using it as a verb (the verb is 'to oscillate').
