Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'омега-3 жирная кислота' in very formal scientific Russian, where 'омега-3-ненасыщенная жирная кислота' is more precise.
- Do not confuse with 'жирные кислоты' (fatty acids) in general – the 'omega-3' specifies the type.
Common Mistakes
- Pronouncing 'omega' as /ˈɒmɪɡə/ instead of /oʊˈmeɪɡə/ (US) or /ˈəʊmɪɡə/ (UK).
- Using it as a countable noun incorrectly: 'an omega-3' (less common) vs. 'omega-3s' or 'omega-3 fatty acids'.
- Misspelling as 'omega-3 fatty acids' (plural) when used as a general uncountable concept.
