Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'предельная линия' which is overly literal. In nautical contexts, 'грузовая марка' (load line/Plimsoll line) is the direct equivalent. 'Граница допустимого' captures the metaphorical sense.
Common Mistakes
- Using 'margin line' to mean 'a line in the margin of a text' (that's a 'marginal line').
- Confusing it with 'bottom line' (financial result).
- Using it as a verb (e.g., 'to margin line' is incorrect).
