Commentary
After the root हनु 'to kill' when in construction with a case-inflected word as its उपपद and when used without a preposition comes the affix क्यप् in denoting condition and the letter त is the substitute of its final.
The phrases सुपि अनुपसर्गे and भावे are understood in this sutra.
As ब्रह्म + हन् + क्यप् = ब्रह्म + हत् + य = ब्रह्महत्य, 6.1.71 ब्रह्महत्या 'Brahman- murder'. So also अश्वहत्या 'killing a horse'.
When not in construction with a noun, the form is घातः 'a blow' (हन् + णिच् +घञ्). This verb does not take the affix ण्यत् in denoting condition, there being no example of such formation.
Why do we say 'when not taking a preposition'? Observe प्रघातो वर्तते 'there is a combat'.
