The finite verb optionally retains its accent after jātu when this jātu is not preceded by another word.,
Thus जा꣡तु भोक्ष्य꣡से, जातु अध्यष्य꣡से, जातु करिष्या꣡मि । Here से is anudatta by 6.1.186, as it is an Sarvadhatuka affix coming after an अदुपदेश; the word जातु is first acute, as it is a Nipata. Why do we say 'when not preceded by any other word'? Observe:- कटं जातु क॒॒रि॒॒ष्य॒॒ति॒॒ ॥ The word कटं is end-acute as it is a फिट् or noun.,
