Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'биологический' (correct) and 'био логичный' (incorrect). The Russian word covers all meanings directly. Be careful with 'biological parent' vs. 'родной родитель' (native parent) – 'biological' is more specific.
Common Mistakes
- Misspelling as 'biologic' (adj. is rare, 'biological' is standard). Using 'biological' to mean 'ecological' (e.g., 'biological tourism' is wrong, use 'eco-tourism').

FAQ
Frequently Asked Questions
Not exactly. 'Biological' specifically relates to living organisms or their study. 'Natural' is broader and can include non-living things (e.g., natural disaster). A 'natural substance' could be mineral; a 'biological substance' must come from a living thing.
'Biological' is the standard adjective. 'Biologic' is a less common variant, often used in specific medical/pharma contexts (e.g., 'biologic drug'). Learners should use 'biological'.
Yes, absolutely. It applies to all living organisms (e.g., biological diversity, biological processes in plants, biological warfare using bacteria).
It is a standard, factual term. However, in sensitive family discussions (e.g., adoption), terms like 'birth mother/father' or simply 'mother/father' (depending on context) may be preferred for their less clinical tone. Context and sensitivity are key.
