Etymology
Origin of regress
First recorded in 1325–75; Middle English regresse (noun), from Latin regressus “a return,” noun use of past participle of regredī “to go back, return,” from re- re- + -gredī, combining form of gradī “to step, walk, go”; cf. gradient
Explanation
To regress is to return to a former state or condition, and not usually in a good way. It often means "relapse" or "get worse." First used in the late 14th century as a noun meaning "act of going back," regress originates from the Latin regress, meaning "a return." Many feel that the regress to anti-social behavior among teenagers is caused by violent video games, TV shows, and movies. A 30 year old forced to move back home may regress to old, childlike habits. It can also happen to someone's health, like when the condition of someone in recovery takes a turn for the worse.
