ind. (ablative feminine singular of the locative absolute construction pisuṇavācāpaccaya-)
Analysis. pisuṇa-vācā-paccayā: pisuṇa (divisive, from √piṃs "split, separate") + vācā (speech, from √vac "speak") + paccayā (ablative of paccaya "condition, reason", from pac "to bind, connect"). The compound treats pisuṇavācā (divisive speech) as the condition or causal ground; the ablative marks it as an instrumental cause.
Etymology. pisuṇa: from √piṃs (to split, separate, pierce), cognate with Latin findere (to split) and Sanskrit piṃsati; the sense moved from physical splitting to sowing discord. vācā: from √vac (to speak), cognate with Latin vox (voice) and English voice. paccaya: from √pac (to bind, connect, join), related to Sanskrit paśyati; the underlying image is "that which binds or holds together as a reason."
