Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ethernet' or 'aesthetic' terms.
- The '-ify' ending relates to the process of making something, similar to 'классифицировать'.
Common Mistakes
- Incorrect: 'esterisation' (correct: 'esterification').
- Confusing the agent: 'The alcohol esterifies the acid' is acceptable, but it's the reaction process itself.
