What does candlenut mean?
The candlenut is the seed of Aleurites moluccanus, a fast-growing tropical tree native to Southeast Asia and widely spread across the Pacific by early Polynesian voyagers. Its name reflects its most famous historical use: the kernels are so rich in oil that they burn steadily when lit, and Pacific islanders strung them together to serve as candles and torches. The tree, known in Hawaiian as kukui, was valued far beyond illumination — its oil waterproofed cloth and canoes, its bark yielded dye, and its nuts provided food once roasted. In modern usage, the word 'candlenut' appears chiefly in three contexts: botany and horticulture, where it names the tree; Hawaiian and Polynesian cultural references, including leis and traditional crafts; and Southeast Asian cuisine, where ground roasted candlenuts thicken sauces and curries, particularly in Indonesian and Malaysian cooking. Because raw nuts contain mildly toxic compounds, they are never eaten uncooked. The candlenut holds special status in Hawaii as the official state tree.
nounThe oily seed of the candlenut tree (Aleurites moluccanus), a tropical Asian and Pacific tree of the spurge family, so called because the seeds were traditionally burned as candles. The tree itself is also referred to by this name.
- The large, oily seed of Aleurites moluccanus, used historically as a source of light and oil, and in Southeast Asian cooking (often roasted).
- The candlenut tree itself (Aleurites moluccanus), native to tropical Asia and the Pacific.
"In old Hawaii, strung candlenuts served as torches, burning late into the night."
"The Polynesians carried the candlenut across the Pacific, relying on its oily kernels both as food and as fuel for lamps."
"Ground roasted candlenuts give Indonesian and Malaysian curries their characteristic thick, rich texture."
"Shaded by towering candlenuts, the beach road wound along the coast of Maui."
Regular plural formation; the plural refers to multiple seeds or, less often, multiple trees.
"The villagers harvested baskets of candlenuts each autumn."
The candlenut is Hawaii's official state tree, and its seeds burn so richly in oil that islanders once strung them together to make natural candles.

Etymology of candlenut
The English name 'candlenut' arose in the late 17th or early 18th century from the combination of 'candle' and 'nut', coined by European observers who learned that Pacific islanders burned the oily seeds as lamps. The compound follows a transparent English pattern of naming plants after their uses. Its closest linguistic relatives are therefore other compounds built on 'candle', which descends from Old English 'candel', ultimately from Latin 'candela'.
How candlenut is actually used
The word appears most often in botanical, culinary, and Hawaiian/Pacific cultural contexts rather than everyday speech. In Hawaiian, the tree and nut are known as kukui, and the term 'kukui nut' is often preferred locally. In Southeast Asian cookery, candlenuts are always roasted or cooked before eating, as raw seeds are mildly toxic.
