4.44

蔓延（上無怨反韻英蔓謂苽[瓜*夸]之苗也下延爾雅曰延長也延引也案蔓延如蔓草連延長引不絕也下延又作莚音餘戰反廣雅云蔓長也莚遍也二字皆從草）。

蔓延 (for the first character, [màn], fanqie 無怨 [m- + -ʉɐn = mʉɐn/màn]. The Yunying says: “蔓 refers to the sprouts of melons.” For the second character, 延, the Erya says: “延 means long; 延 means to draw out.” It is noted that 蔓延 is like creeping vines spreading and drawing out without break. The second character 延 is also written 莚, pronounced 余戰 [j- + -iɛn = jiɛn/yán]. The Guangya says: “蔓 means long; 莚 means widespread.” Both characters take 草 as radical.)
