Common Pitfalls
Translation Traps (for Russian speakers)

- The '-wich' in Greenwich is pronounced /ɪtʃ/, not /wɪtʃ/.
- Do not confuse with the 'Pulkovo Observatory' (Пулковская обсерватория) as the Russian equivalent.
Common Mistakes
- Incorrect: 'Royal Greenwich Observatory' (forgetting capitalization).
- Incorrect: 'Greenwich Royal Observatory' (incorrect word order).
- Incorrect pronunciation: /ˈɡriːn.wɪtʃ/ instead of /ˈɡren.ɪtʃ/.
