Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate component parts ('azido', 'thymidine') literally. It is a fixed international pharmaceutical name.
- The common Russian term is 'зидовудин' (zidovudin) or 'АЗТ' (AZT). Translating it as 'азидотимидин' would be a direct transliteration, not the standard term.
Common Mistakes
- Misspelling as 'azidothimidine' (missing the 'y').
- Incorrect pronunciation stressing 'azo-' instead of 'azi-do-'.
- Using the full term 'azidothymidine' in casual conversation instead of 'AZT'.
