Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'аквариум' – it's a direct cognate with identical meaning. No trap, but note pronunciation differences: Russian stress is on 'а', English on the second syllable.
Common Mistakes
- Spelling: 'aquaruim' (misplacement of 'u'), 'akvarium' (non-Latin spelling).
- Plural: Overusing 'aquaria' in casual speech.
- Article use: 'I went to aquarium' (missing 'the' for a specific institution).
