कृदतिङ्
SV: कृत् अतिङ्
AV: तत्र
Language Meaning: In this portion of the sūtras in which there is a reference to verbal roots, any affix except तिङ् - tense affixes, is called कृत्
Commentary - This could have been inserted after तिङ् प्रत्यय evolved. It could be earlier also, who knows? But predation to तिङ् seems extremely unlikely unless तिङ् means literal तिङ्. तिङ् means तिङ् (tumbi below outward) here and could have been seed for later तिङ् (float below outward) प्रत्यय evolution.
Literal Meaning: क ऋ द त इ ङ
(hand hold / stome) superior give tumbi (object/below) outside/periphery
