- Do not confuse with 'адреналин' (direct equivalent) – but note that in Russian, 'адреналин' is used both medically and colloquially, similar to English.
- Avoid literal translations like 'гормон страха' (hormone of fear) – adrenaline is not only about fear.
Common Mistakes
- Misspelling as 'adrenalin' (without the final 'e' is an older variant but less common).
- Using 'adrenaline' as a verb (non-standard; use 'pump with adrenaline' or 'get adrenaline').
