C2Academic, Technical, Scientific
Definition
Meaning
A large and economically important plant family (Fabaceae/Leguminosae) characterized by seed pods that split along two seams, whose seeds are often eaten.
The taxonomic group of plants also known as Fabaceae, which includes peas, beans, lentils, peanuts, clover, alfalfa, and many trees and shrubs; often used in contexts of botany, agriculture, nutrition, and gardening.
Linguistics
Semantic Notes
The term is a scientific/technical name for a botanical family. In non-technical contexts, people are more likely to name specific members (e.g., peas, beans) or use the informal 'legumes'.
Dialectal Variation
British vs American Usage
Differences
No significant usage differences; the term is standard in scientific English globally. The alternative family name 'Fabaceae' is preferred in formal botanical contexts, while 'Leguminosae' is also accepted.
Connotations
Neutral and technical in both varieties.
Frequency
Equally low-frequency in general discourse, but standard in agricultural, botanical, and nutritional texts in both regions.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'семья бобовых'. The correct Russian equivalent is the established term 'семейство бобовых'.
- In Russian, 'бобовые' often refers to the edible seeds/pulses, while in English 'legume family' refers strictly to the botanical family.
Common Mistakes
- Using 'legume' as an adjective for the family (e.g., 'legume plants') instead of the noun phrase 'legume family'.
- Confusing 'legume' (the plant/seed) with 'legume family' (the taxonomic group).

FAQ
Frequently Asked Questions
'Legume' typically refers to the plant or its edible seed (e.g., a bean). 'Legume family' is the scientific name for the entire botanical family (Fabaceae) to which these plants belong.
No. While many important food crops (beans, peas, lentils) are members, the family also includes non-edible ornamental plants, forage crops like clover, and trees like acacia.
Many plants in this family form a symbiotic relationship with bacteria that 'fix' atmospheric nitrogen into the soil, naturally enriching it and reducing the need for synthetic fertilisers.
No. 'Pulses' are specifically the dried edible seeds of legume plants (e.g., dried lentils, chickpeas). 'Legume family' is the broader botanical category that includes pulses, fresh peas/beans, forage crops, and trees.
