nightshade family
LowTechnical / Scientific
Definition
Meaning
The taxonomic family Solanaceae, comprising flowering plants, many of which contain alkaloids.
A large plant family including important food crops (tomatoes, potatoes, peppers, aubergines) and toxic/medicinal species (belladonna, jimsonweed, tobacco). The term can be used metaphorically to denote a group with both beneficial and dangerous members.
Linguistics
Semantic Notes
Primarily a botanical term. In non-technical contexts, 'nightshade' alone typically refers to the toxic species (e.g., deadly nightshade), whereas 'nightshade family' is a broader classification including common edible plants.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling of 'aubergine' (UK) vs. 'eggplant' (US) when citing an example member.
Connotations
Identical technical connotations. In gardening/food contexts, US speakers may use the phrase 'nightshade vegetables' more frequently than UK speakers.
Frequency
Equally low frequency in both dialects, confined to botany, horticulture, and related discussions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'ночная семья'. The correct equivalent is 'паслёновые' (scientific) or 'семейство паслёновых'.
- The word 'nightshade' alone ('паслён') in Russian often refers only to the toxic weed, not the entire family, which can cause confusion.
Common Mistakes
- Using 'nightshade' to mean the entire family in non-technical contexts, causing confusion with the poisonous plant.
- Misspelling as 'night shade family' (two words for 'nightshade').
