Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'близкий' (close/emotionally near). 'Adjacent' is more 'смежный' or 'прилегающий'.
- Do not use for abstract 'близкие по духу' ideas unless in a technical metaphor.
Common Mistakes
- Using 'adjacent' for things that are merely nearby but not sharing a boundary/side.
- Incorrect preposition: 'adjacent with' (correct: 'adjacent to').
- Overusing in informal contexts where 'next to' suffices.
