The words सप्तम्याः and काले are understood here. The base, the substitute, the affix, the particular time &c, must all be deduced from these forms. Thus सद्यः is formed from समान, by substituting स for समान, and adding the affix द्यस्; in the sense of 'a day'. समानेऽहनि = सद्यः 'the same day'. The पूर्व and पूर्वतर are replaced by पर, and then the affixes उत् and आरि are added, in the sense of 'a year'. Thus पूर्वस्मिन् संवत्सरे = परुत् 'last year'. पूर्वतरे संवत्सरे = परार 'the year belore last'. The इश replaces इदम्, and affix समतण् is added, in the sense of 'year'. Thus अस्मिन् संवत्सरे = ऐषमः 'during this years'. To पर is added एद्यवि in the sense of 'a day': as, परस्मिन्नहनि = परेद्यवि 'the other day'. The अद्य replaces इदम् and the affix द्यस् is added in the sense of 'a day'. Thus अस्मिन्नहनि = अद्य 'to day'. To the words पूर्व, अन्य, अन्यतर, इतर, अपर, अधर, उभय and उत्तर is added the affix एद्युस्, in the sense of 'a day': as पूर्वस्मिन्नहनि = पूर्वेद्युस् 'on the day before', अन्यस्मिन्नहनि = अन्येद्युस् 'on the following day'. अन्यतरस्मिन्नहनि = अन्यतरेद्युः 'on either of two days'. इतरस्मिन्नहनि = इतरेद्युः 'on another day', अपरस्मिन्नहनि = अपरेद्युः 'on the following day', अधरस्मिन्नहनि = अधरेद्युः 'on a previous day'. उभयोरहनोः = उभयेद्युः 'on both days'.,
