yellowing の語源・成り立ち Etymology
古英語geolu（黄色い）に動名詞接尾辞-ingが付いた語。ゲルマン祖語*gelwazに遡り、ラテン語helvus（淡黄色）やギリシャ語khlōros（黄緑）と同根。関連語はyellow、gold。紙や布が経年で黄色く変色する現象を指す。
Yellowing consists of yellow plus the noun-forming or participial suffix -ing. Yellow descends from Old English geolu and is related to other Germanic words derived from a root associated with yellow and yellow-green colors. Distant cognates include Latin helvus, meaning pale yellow, and Greek khlōros, referring to a greenish-yellow shade. The -ing form came to denote both the process of becoming yellow and the discoloration resulting from that process.
