Commentary
When a word ending in the Locative -7th case does not denote time preserves its original accent when followed by 1. सिद्ध 2. शुष्क 3. पक्व and 4. बन्ध in a compound.
Thus सांकाश्य꣡सिद्धः or सांका꣡श्यसिद्धः, काम्पिल्य꣡सिद्धः or काम्पि꣡ल्यसिद्धः ॥ The words samkasya and kampilya have acute on the final, and by Phit Sutra (III.16) in the alternative the accent falls on the middle also. So also निध꣡नशुष्कः, ऊक꣡शुष्कः ॥ The word निधन is derived by क्यु affix added to नि-धाञ् and has acute on the middle; the word ऊक is formed from अव् root by the affix कक्, and has acute on the final. So also भ्रा꣡ष्ट्रपक्वः, कुम्भी꣡पक्वः, कलशी꣡पक्वः ॥ The words Kumbhi and Kalasi are formed by ङीष् affix and have acute on the final; the word भ्राष्ट्र is formed by ष्ट्रन् affix, and has acute on the beginning. So also चक्र꣡बन्धः चा꣡रकबन्धः ॥ The word chakra has acute on the final, and charaka being formed by ण्वुल् has acute on the first.
Why do we say 'when not denoting time'? Observe पूर्वाह्णसिद्धः꣡, अपराह्णसिद्धः꣡ ॥ The compounding takes place by 2.1.41. The accent of the Locative Tatpurusha taught in 6.2.1 was debarred by Krit-accent taught 6.2.144. The present sutra debars this last rule regarding Krit accent, and reordains the Locative Tatpurusha accent when the Krit-words are सिद्ध &c.
