Commentary
When आत्मनेपद affixes follow, वध् is optionally the substitute of हन् in the लुङ् (Aorist).
Thus आवधिष्ट or आहत; आवधिषाताम् or आहसाताम्; आवधिशत or आहसत.
The verb हन् becomes Atmanepadi when preceded by आ 1.3.28 By sutra 1.1.14, the Aorist-affixes in the Atmanepada are कित् and हन् and by 6.4.37 the न is elided before कित् affixes then by 8.2.27 the स is elided. Thus आहन् + सिच् + त = आहत.
