water pepper

Definition
Meaning
A common name for several species of plants in the genus Persicaria, especially Persicaria hydropiper, a herbaceous annual plant found in wet, marshy areas, known for its peppery-tasting leaves.
The term can refer to the plant itself, its leaves used as a pungent herb, or, historically, as a medicinal plant. It is sometimes called 'smartweed' or 'marsh pepper'.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'водяной перец' without context, as this is the established Russian name for the plant. It is not a type of pepper (перец) in the culinary sense. The English term is a fixed name, not a descriptive phrase.
Common Mistakes
- Using it as a mass noun (e.g., 'add some water pepper') like culinary pepper. It's a countable plant name (e.g., 'a water pepper').
- Confusing it with 'watercress', which is a common edible aquatic plant.
- Capitalising it as a proper noun (unless starting a sentence).
