Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation to "ударять" (to hit) in most contexts. The primary sense is figurative encroachment. Closer concepts: "посягать на" (encroach upon), "вторгаться в" (intrude into), "влиять негативно на" (affect negatively).
Common Mistakes
- Using without a preposition (e.g., 'It impinges our rights' - incorrect).
- Confusing with 'infringe' (they are synonyms, but 'impinge' is more often intransitive + 'on').
- Using in overly casual contexts where 'affect' would suffice.
