ब्राह्मो ऽजातौ

This sutra should be divided into two (1) ब्राह्मः, the final अन् of ब्रह्मन् is elided, when the अण् affix with the force of the Patronymic, as well as with any other force, comes after it. Thus ब्राह्मो गर्भः, ब्राह्मं हविः, ब्राह्ममस्त्रम्; ब्राह्मो नारदः ॥ (2) अजातौ, but not so, when the Patronymic denotes a jati; for then the अन् of ब्रह्मन् is not elided before the अण् affix : as ब्रह्मणोऽपत्यं = ब्राह्मणः 'a Brahmana'. When jati is expressed, but अण् has not the force of the Patronymic, the अन् of ब्रह्मन् is elided. As ब्राह्मी औषधिः ॥,
