147. The aspiration

The aspiration ह् h is not allowed to maintain itself, but (like ज् j and श् ç) either reverts to its original guttural form, appearing as क् k, or is changed to ट् ṭ—both in accordance with its treatment in inflection: see below, 222. And, also as in inflection, the original sonant aspiration of a few roots (given at 155b) reappears when their final thus becomes deaspirated. Where the ह् h is from original ध् dh (223e), it becomes त् t.
