Analysis. From ya (relative pronoun/conjunction) + -to (ablative suffix). Yato combines the relative sense of ya with ablative force: "from which" → "since" (causal), "wherever" (locative-ablative extension).
Etymology. Ya is the ancient relative pronoun, cognate with Sanskrit ya-, Greek hós (Latin quī from *quo-i-), Gothic hwas, English who. The ablative -to derives from Indo-European *-tod (seen in Latin istud "that", Sanskrit tad "that"). Together they build the causal and locative-relative adverb central to Pali narrative and doctrinal prose.
