焦炷（上即姚反鄭注禮記云焦臭也廣雅云焦黑也說文從隹從火經文中多作燋音即藥反案燋者灼龜之木也非經義下炷音注案炷者燈焰下焦炷字近代出說文內無亦是形聲字也）。

Burnt wick (焦炷: the first character has the fanqie 即姚反; Zheng [Xuan's] commentary on the Liji states: "Jiao (焦) means scorched smell." The Guangya states: "Jiao means blackened." The Shuowen jiezi states: "From the bird radical (隹) and the fire radical." Sūtra texts often write it as 燋 (fanqie 即藥反); note that 燋 refers to the wood used for scorching tortoise carapaces, not the sūtra's meaning. The second character, 炷, has the sound 注; note that a wick (炷) refers to the burnt wick beneath a lamp's flame. The character appeared in modern times and is not found in the Shuowen jiezi; it too is a picto-phonetic character).
