Etymology

Origin of cassava

First recorded in 1545–55; from Spanish cazabe “cassava bread or meal,” from Taíno caçábi

Explanation

Cassava is a starchy tuber that comes from a South American shrub of the same name. In tropical countries, cassava is a common staple food. The most cassava is grown and eaten in Nigeria, and it's popular in many places because it grows even when there's not much rain or the soil is poor. Experts estimate that 800 million people depend on cassava. It has to be properly prepared to be safely eaten, either cooked like potatoes or ground into a coarse meal or fine flour. Tapioca, a starch found in pudding and bubble tea, is also made from cassava.
