The affix ṭhañ comes in the remaining senses after the word śarad when expressing śrāddha,
This debars अण् 4.3.16. The word श्राद्धे means the 'funeral oblation'; and not श्रद्धावान् पुरुषः 'a faithful or believing person'. Thus शारदिकं श्राद्धं 'the autumnal Sraddha'. When not meaning 'Sraddha', it will be शारदम् ॥,
