Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'скала' (cliff/rock face) or 'фундамент' (man-made foundation). The closest is 'коренная порода' (literal) or 'основа', 'фундамент' (figurative, but implies natural, not constructed).
Common Mistakes
- Using it as an adjective (*'a bedrock idea') – it's primarily a noun. Confusing it with 'cornerstone' (which is one key part, whereas 'bedrock' is the whole foundation).
