Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'равноденственные дожди'. This is a calque. Use the established term 'дожди в период равноденствия' or the descriptive 'сезонные ливни (в период равноденствия)'.
- Avoid confusing with 'проливной дождь' (downpour) which lacks the specific seasonal timing.
Common Mistakes
- Using it for any heavy rain. *'We got caught in the equinoctial rains on the way to the shops.' (Incorrect unless it's actually the equinox).
- Spelling: 'equino**x**ial rains' (incorrect).
