What does alfalfa mean?
Alfalfa is a deep-rooted perennial plant of the pea family, Medicago sativa, grown throughout the temperate world as one of the most important forage crops. Rich in protein, vitamins, and minerals, it is cut and dried as hay or grazed directly by cattle, horses, and sheep, and it plays a valuable agronomic role because its nitrogen-fixing roots improve soil fertility. In British English the same plant is usually known as lucerne, while alfalfa is the standard North American name. Beyond the farm, the word entered popular vocabulary through alfalfa sprouts, the slender young shoots that became a staple of sandwiches and salads in health-food circles. The term itself has an unusually well-traveled history: it passed from Arabic into Spanish and then into English, carrying with it centuries of agricultural tradition. For anyone reading about farming, nutrition, or rural life, alfalfa is a word worth knowing.
nounA deep-rooted perennial plant of the pea family (Medicago sativa), grown widely as a forage crop and fed to livestock as hay, pasture, or silage; its young shoots are also eaten by humans as sprouts.
- The perennial leguminous plant Medicago sativa, cultivated chiefly as fodder for cattle and horses.
- The dried herbage (hay) of this plant used as animal feed.
"The farmer rotated his corn fields with alfalfa to restore nitrogen to the soil."
"Dairy cows thrive on a diet of fresh alfalfa."
"She topped her sandwich with a handful of crunchy alfalfa sprouts."
Rarely pluralized; the singular is almost always used even when referring to multiple plants or fields.

Arabic farmers called it al-fasfasa, 'the best fodder' — a name so prized it traveled through Spanish into English essentially unchanged.

Etymology of alfalfa
Alfalfa entered English in the early nineteenth century from Spanish, where the plant had been cultivated after its introduction during the Moorish period. The Spanish word derives from the Arabic al-fasfasa, meaning 'the best fodder,' reflecting the plant's long-standing reputation as premier livestock feed. The crop itself originated in western Asia and was spread across Europe and eventually the Americas, so the word's journey mirrors the plant's own remarkable migration.
How alfalfa is actually used
In British English the plant is more often called lucerne; 'alfalfa' is the standard term in North American English. The word carries wholesome, agricultural connotations, and 'alfalfa sprouts' became a byword for health-food culture in the late twentieth century.
