A disyllabic Participle in ta (niṣṭhā) when a Name has the acute on the first syllable, but not if the first syllable has an ā,
Thus गु꣡प्तः, बु꣡द्धः, द꣡त्तः ॥ This debars the affix accent 3.1.3. In non-participles we have देवः꣡, भीमः꣡ ॥ In polysyllabic Participles we have चिन्तितः꣡, रक्षितः ॥ In Participles having long आ in the first syllable, we have, त्रातः꣡, आप्तः꣡ ॥ When the Participle is not a Name we have, कृत꣡म्, हृत꣡म् ॥,
