Etymology

Origin of region

First recorded in 1300–50; Middle English, from Anglo-French regiun, from Latin regiōn-, stem of regiō “direction, line, boundary,” from reg(ere) “to make straight, guide, rule” + -iō -ion

Explanation

A region is an area. A region can be geographic — like a part of a country. A region can be intellectual — like a region of the mind. There are also bodily regions — like abdominal, thoracic, and posterior. A region is any space that is distinct from another area. The word region is from the Latin regionem which means “direction, boundary, district.” When you go to California you may want to travel north to the wine region, which will stimulate the taste-receptor region of your brain. After that, if you go south to the filmmaking region of Hollywood, you will excite the “movie-and-entertainment” region of your mind.
