/kyap comes (optionally) after eti एति stu स्तु zas शस् vR वृ dR दृ juS जुष्.

This /kyap is a /kRtya affix, so it means "that should be".

The /kit is for kGitica.

The /pit is for accent and for triggering hrasvasyapit....

iN इण् + /kyap → !**ityaH- इत्यःॱ "to be gone to", with t त् by hrasvasyapit...

zAs शास् + /kyap → !**ziSyaH- शिष्यःॱ "to be instructed", "pupil", with zis शिस् by zAsa::idaGh...

Why do you translate vR वृ as vRJ वृञ्?

Because vRG वृङ् makes vArya- वार्यॱ, so it has /Nya or something, I guess.
