Examples
By CEFR Level
- This word is too advanced for A2 level.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque from Russian зигота (zigota) as the primary translation should be 'zygote'. 'Oosperm' is a very specific, less common synonym.
- Do not confuse with just 'sperm' (сперматозоид).
Common Mistakes
- Using 'oosperm' to refer to an unfertilized egg. It specifically requires fertilization.
- Using it in non-scientific contexts where 'fertilized egg' would be clearer.
- Misspelling as 'oosperme' or 'oospermia' (the latter is a medical condition).

It would be very unusual and confusing. In everyday language, terms like 'fertilised egg' are much clearer.
Not in common use. The related adjective would typically be 'zygotic' (e.g., zygotic development).
