However, there is an exception. When the second letter is r-, the -ḥ disappears; the vowel in front of it, if it is i or u, becomes long. If the visarga originally came from the letter -r, then an a becomes long, too.

Irregular -ḥ sandhi: saḥ and esaḥ

This special rule apply to tad and etad in the masculine singular of case 1. They apply to no other words.

In front of a vowel, saḥ and eṣaḥ behave normally. In front of a consonant, saḥ becomes sa and eṣaḥ becomes eṣa.
