Translation Traps (for Russian speakers)
- Do not confuse with Russian 'онагр' (onagr), which is a direct loanword with the same meaning. It is an extremely low-frequency word in Russian as well. The word 'onager' is not related to 'ондатра' (ondatra - muskrat).
Common Mistakes
- Pronouncing it as 'oh-NAY-jer'. The stress is on the first syllable: 'ON-uh-jer'.
- Confusing it with 'orangutan'.
- Using it as a general term for any wild donkey.
