The A आ of these verbbases disappears before most vowel apit by znAbhyastayor... —

dadhm- दध्म्

and in the case of /ghu roots before all apit —

dadh- दध्

So we say —

**dadhus दधुस्, **dadhmus दध्मुस्

The A आ together with /Nal (which is /pit) makes /au by Ata::auNalaH —

**dadhmau दध्मौ **dadhau दधौ **dadau ददौ

so it can only stay before /thal —

**dadhAtha दधाथ

but this /thal can always be optionally ithal इथल्, and then the A आ disappears anyway —

**dadhitha दधिथ "you gave" with loss of A आ by Atolopa::...
