Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'галлюцинаторный' (hallucinatory). 'Hallucinogenic' означает 'вызывающий галлюцинации', а 'hallucinatory' — 'относящийся к галлюцинациям, галлюцинаторный'.
- Прямой перевод 'галлюциногенный' является точным и используется.
Common Mistakes
- Misspelling: 'halucinogenic' (one 'l'), 'hallucigenic'.
- Using as a verb (e.g., 'It hallucinogeniced me' – incorrect).
- Confusing with 'hallucination' (the experience) vs. 'hallucinogenic' (the cause).
