Definition
Meaning
A family of plants characterised by prickly, often spiny fruits or seeds.

Linguistics
Semantic Notes
The term is primarily used in botany and horticulture. The 'caltrop' in the name refers to the similarity of the plant's spiny fruit to the multi-spiked metal weapon designed to injure feet and hooves.

Examples
By CEFR Level

Learning
Memory Aids

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct translation like 'семейство калтропов'. The correct botanical term in Russian is 'Парнолистниковые' (Zygophyllaceae). The descriptive 'колючеплодные растения' (prickly-fruited plants) may be used for explanation.
Common Mistakes
- Misspelling as 'caltrap family'.
- Confusing it with a general term for any spiky plant.
- Using it in non-technical contexts where simpler terms like 'prickly weed' would suffice.
