noun REG Rare

Origin: From Arabic rajm or Maghrebi Arabic reg, a type of desert terrain.

Usage Note

Reg is a geographical term for a flat, stony desert plain swept clean of sand by the wind, characteristic of the Sahara. It contrasts with erg (m), which is the sandy, dune-covered type of desert. The word is used in French physical geography and is borrowed from North African Arabic. Both reg and erg are frequently encountered in school geography in French-speaking countries.
