The Hawaiian Word of the Day is kiawe. Kiawe is the Hawaiian name for the Algaroba tree, a species of the mesquite tree, which was introduced to Hawai'i in the 19th century. It is said that the very first Kiawe tree in Hawai'i was planted at the Catholic Cathedral of Honolulu in 1827 by Hawai'i first Catholic priest, Father Bachelot. In Hawai'i, the kiawe tree is considered an invasive species, but its wood has been useful firewood for cooking and heating. The Hawaiian Word of the Day is kiawe.
