箭筈（煎線反。俗字也。正體作箭。從竹從止從舟蔡邕加刂音古外反。刂水也。可以行舟。後因行草變止止變舟為月變刂為刀漸訛謬也。考聲云箭者本竹名也。案此竹葉似葦藂生高五六尺。莖細勁而且實可以為𠂕笴笴千且反因名矢為箭故說文云箭𠂕也。從竹前聲也下𥹺活反考聲箭口也案箭筈者受弦之口也。經文從水作栝亦通說文從竹從栝省聲也栝音同糠栝也勁音逕）。

箭筈 (Arrow nock: [箭 has the] fanqie 煎線 [jiàn]; this is a vulgar character. The standard form is written 箭, derived from 竹 [bamboo], 止, and 舟 [boat]. Cai Yong added 刂, with the fanqie 古外 [guài]; 刂 represents water, allowing a boat to travel. Later, through running and cursive scripts, 止 was corrupted, 舟 became 月, and 刂 became 刀, gradually becoming corrupt and erroneous. The Kaosheng says: '箭 was originally the name of a bamboo.' Examining this, its leaves resemble reeds, growing in clusters five or six feet high; its stems are slender, sturdy, and solid, suitable for arrow shafts (笴 has the fanqie 千且 [qiǎn]), and therefore arrows were named 箭. Thus the Shuowen jiezi says: '箭 means arrow; derived from 竹 with the sound 前.' The lower character has the fanqie 𥹺活 [kuò]. The Kaosheng says: 'The opening of an arrow.' We note that the arrow nock is the opening that receives the bowstring. The sūtra text writing it with the water radical as 栝 is also acceptable. The Shuowen jiezi derives it from 竹 with the abbreviated sound 栝. 栝 has the same sound as the kuò in tangkuo [quern-scraper]. 勁 has the sound 逕 [jìng]).
