17.139

方便殺中，云尸半等者，泰云：有人欲殺他，呪令死身長，令殺怨家故名尸。呪無頭尸，不作語言令殺他人故名半尸。

In preliminary effort of killing, where it mentions 'corpses and half-[corpses],' etc., Tai says: someone wishing to kill another incants a dead body to grow tall, causing it to kill the enemy, hence it is called a 'corpse.' Incanting a headless corpse that makes no speech, causing it to kill another, is called a 'half-corpse.'
