Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- In Russian, 'аспирин' (aspirin) is the common term, and 'ацетилсалициловая кислота' is the formal equivalent. A direct word-for-word translation of the full English term is correct and understood, but using 'aspirin' in casual English is more natural.
- Be careful not to confuse 'acid' (кислота) with 'ase' (-аза) which is an enzyme suffix in both languages.
Common Mistakes
- Mispronunciation: stressing the wrong syllable (e.g., /ˈæsɪtɪl.../ instead of /əˌsiːtəl.../).
- Misspelling: 'acetylcylic acid', 'acetylsalicilic acid'.
- Overuse in everyday contexts where 'aspirin' is expected, making speech sound overly technical.
