Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'осциллировать' in everyday speech; it's a technical loanword. For emotions/opinions, use 'колебаться' or 'метаться'. For physical movement, 'качаться' or 'совершать колебания'.
Common Mistakes
- Using 'oscillate' for a one-time change (incorrect: 'He oscillated to a new opinion.'). Confusing with 'osculate' (to kiss).
