Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'acid' as 'кислота' in a corrosive sense; it's a specific organic compound. The term is a fixed calque: 'эллаговая кислота'.
Common Mistakes
- Pronouncing it as 'e-lagic' (like 'magic') instead of 'el-laj-ic'.
- Confusing it with other acids like folic acid or ascorbic acid.
- Using it as a countable noun (e.g., 'an ellagic acid') – it's non-count.
