The ending of the middle participle is āná. It is added to the weak form of perfect-stem, as this appears in the middle inflection: thus, बुबुधान bubudhāná, निन्यान ninyāná, ददानdadāná, तेनान tenāná, जज्ञान jajñāná, उचान ūcāná.

a. In the Veda, the long reduplicating vowel is shown by many middle participles: thus, vāvṛdhāná, vāvasāná, dādṛhāṇá, tūtujāná, etc. RV. has çaçayāná from √çī (with irregular guṇa, as in the present-system: 629); tistirāṇá from √stṛ; and once, with māna, sasṛmāṇá from √sṛ. A few participles with long redupl. vowel have it irregularly accented (as if rather intensive: 1013): thus, tū́tujāna (also tūtujāná), bā́badhāna, çā́çadāna, çū́çujāna, çū́çuvāna.
