Definition: the same as Antaraṅga Paribhāṣā or the doctrine of the invalidity of the bahiraṅga operation. See the word असिद्ध above. For details see the Paribhāṣā 'asiddham, bahiraṅgam antaraṅge' Par. Śek. Pari. 50 and the discussion thereon. Some grammarians have given the name असिद्धपरिभाषा to the Paribhāṣā असिद्धं बहिरङ्गमन्तरङ्गे as contrasted with अन्तरङ्गं बहुिरङ्कगाद् वलीयः which they have named as बहिरङ्गपरिभाषा.
