The acute accent is on the first syllable of pathin and mathin when followed by a strong case-ending.,
The words पथिन् and मथिन् are derived by the Unadi affix इनि, (IV. 12. and 13) and are oxytone by 3.1.3. They become adyudatta before strong cases. Thus प꣡न्थाः, प꣡न्थानौ, प꣡न्थानः, म꣡न्थाः, म꣡न्थानौ, म꣡न्थानः ॥ Before other cases we have:- पथः꣡ पश्य, मथः꣡ पश्य ॥ The accent is on the final by 6.1.162, there being elision of the udatta इन् ॥ The rule 1.1.62, about the remaining effect of the affix, does not apply here. As पथि꣡प्रियः, has acute on the final of the first word, by retaining its original accent.,
