This is an irregular feature - both in frequency and oddness - dedicated to a word I came across that I have never previously used.
karroo (kah-ROO) n. a semiarid, terrace-like plateau found in regions of South Africa.
The term "karroo" can also be used as a proper noun. Karoo regions of South Africa are divided into the North Karroo - which is along the Orange River - the Great Karroo, and the Little Karroo, which is near the Atlantic coast.
The word karroo is derived from the Khoi word karusa, meaning "dry" or "barren."
