Seeds are the reproductive unit of flowering plants. Legumes belong to the Fabaceae (or Leguminosae) family and produce seeds within pods. This group includes peas, lentils, chickpeas, peanuts, soybeans, and beans. This last subset of legumes, beans, includes black beans, kidney beans, pinto beans, and navy beans. But often people use beans, seeds, and legumes as synonyms. Other seeds are described in a different post.
Chickpeas
Lentils
Slavic languages show a deep divide in the terms used for lentils, with northern Slavs favoring words derived from Proto-Slavic *sočivo, while the southern group primarily uses *lęťa. The latter term, *lęťa, is connected to other European linguistic roots, such as Latin lenticula (a diminutive of lens), and is closely related to terms in Germanic languages. Interestingly, this Slavic term, *lęťa, gained popularity beyond Non-Slavic-speaking regions, like Hungarian (Lencse) and Latvian (lēca), which was later adopted by Estonian. This is just one example of the many linguistic borrowings shown on the map: French lentille to English lentil, Swedish lins to Finnish linssi, and Old Armenian ոսպն (ospn) to Georgian ოსპი (osṗi).
Peas
Romans borrowed from the Greek πίσον (píson), however, it was their Latin term “pisum” that spread around the Mediterranean coast. They also referred to it as “evillia,” a word strikingly similar to the Germanic term, like the German “Erbse” or the Dutch “Erwt.” Are they cognates? Maybe.
In the East, the Proto-Balto-Slavic languages often share a common root. However, in this case, the Baltic languages share their root with the Finnic languages, while the Slavic languages use “gorxъ.” A similar situation occurs in Turkish, which adopted the Latin term via Italian, rather than using the Turkic word “burčak” (originally used for both beans and peas). Hungarians, on the other hand, did adopt it.
Despite the biological differences, the names of legumes are often interchangeable and sometimes confused. For instance, the Persian word نخود (noxod) and Spanish “chícharo” originally referred to chickpeas.
