What does arnut mean?
Arnut is a regional English word for the earthnut, the tuber-bearing plant Lathyrus tuberosus, a member of the pea family. The plant produces small, sweet, nutty tubers that were traditionally dug from hedgerows and field edges and eaten raw or roasted, particularly by children in rural areas before more convenient foods became widespread. The word belongs largely to dialect vocabulary and appears most often today in older natural histories, folkloric accounts, and dictionaries of regional English. Although the plant itself still grows wild across much of Europe, including Britain, the term has fallen out of common use, making it a charming relic of vernacular botanical language. For readers interested in foraging traditions or the history of country words, arnut offers a glimpse into a time when wild plants contributed meaningfully to the rural diet.
nounA dialectal English name for the earthnut or groundnut pea (Lathyrus tuberosus), a plant of the pea family with edible tuberous roots; by extension, the tuber itself, which was once gathered and eaten in parts of Britain.
- The tuberous-rooted plant Lathyrus tuberosus (also called earthnut or groundnut pea).
- The edible tuber of this plant, formerly gathered and eaten in rural Britain.
"The children spent the afternoon digging arnuts from the hedgerow banks to roast over the fire."
"In old accounts of rural life, arnuts are described as being roasted like chestnuts."
"The arnut's pink-flowered vines scramble through the verge in midsummer."
Regular plural; typically used when referring to multiple gathered tubers.
"A basketful of arnuts made a welcome treat after a day in the fields."
Long before peanuts were common in Britain, country children foraged 'arnuts' — sweet little tubers hidden in the hedgerow soil.

Etymology of arnut
The word arnut is a dialectal English formation, apparently blending elements relating to the ground ('ar-', as in earth) with 'nut', reflecting the tuber's nut-like taste. It arose as one of several regional names — alongside earthnut and groundnut — for Lathyrus tuberosus, whose edible tubers were long gathered in the British countryside. It is not related etymologically to the peanut, despite the similarity of the names.
How arnut is actually used
Arnutt is chiefly historical and regional; it survives mainly in dialect dictionaries and older natural-history writing rather than everyday speech.
Easily confused with arnut
A peanut is the seed pod of Arachis hypogaea, a widely cultivated crop, whereas an arnut is the small edible root tuber of the tuberous pea, known mainly as a wild-gathered country food.
