Regression - Regression

Japanese: 回帰 - かいき

〘noun〙① To go around in a circle and return to the original state. To go round again. To repeat. ※Physical History (1875-76)〈translated by Udagawa Junichi〉10 "If we set up a circular line, it is called a return line. After the sun reaches this line, the place where its light shines directly will gradually return towards the equator." ※Farewell to Tanka (1946)〈Usui Yoshimi〉 "Mokichi rather made an effort to avoid returning to such Akahiko-like things." ② In linguistics, it refers to trying to return a word form to its original form that is considered correct. In particular, when this is corrected too much and the form becomes incorrect, it is called a "misguided return."
