袈裟者。蓋從色彰稱也。梵音具云迦羅沙曳。此云不正色○四分律云。一切上色衣不得畜。當壞作迦沙色。今略梵語也又名壞色○業疏云。本作迦沙。至梁葛洪撰字苑下方添衣。言道服也。

Kaṣāya: this name is manifested from its color. The full Sanskrit sound is kāṣāya; here this means an impure color. / The Dharmaguptaka Vinaya states: "Robes of any pure color must not be kept; they should be spoiled into a kaṣāya color." The Sanskrit word is now abbreviated; it is also called a spoiled color. / The Commentary on the Vinaya Deeds states: "Originally it was written as jiasha (迦沙). In the Liang dynasty, when Ge Hong compiled the Ziyuan, he added the robe radical below, signifying a robe of the Way."
