The affix aṇ should be understood to come after whatever we shall teach hereafter up to sūtra tena dīvyati khanati jayati jitam [[4.4.2]] etc.,
Up to aphorism 4.4.2, the affix अण् has a governing influence, except where it is specifically superseded by any particular rule. This aphorism may be looked upon either as an adhikara sutra or a paribhasha sutra or a vidhi sutra. The application of this aphorism will be illustrated throughout the next three chapters. Thus in 4.1.92 तस्यापत्यम् we read the present aphorism and add the affix अण् in the sense of 'his son'. As औपगवः 'the son of उपगुः'; कापटवः 'the son of Kapatu'.
This affix has various meanings, such as, a patronymic 4.1.92, coloured with 4.2.1, sidereal time 4.1.3, revealed sama-veda 4.1.7, covered car 4.2.10 &c.,
