masc nom sg of assa (noun); aor 2nd sg of assi (verb)
Etymology. assa (horse) is unrelated to Sanskrit aśva (horse), which comes from a different Indo-European root (*h₁ek̂-). The Pali word may derive from a lost root meaning 'to move fast' or 'to leap', cognate with English 'ass' (donkey) via a common Italic-Celtic source, though the precise path is uncertain. The noun assa (ashes, dust, corner) appears to be separate, possibly from a root meaning 'to scatter' or 'to break apart'.
