1218. आय्य āyya. With this suffix are made gerundival adjectives, almost only in RV. They have been noticed above (966 c). The ending is everywhere to be read as ā́yia.
a. A few adjectives without gerundival value, and neuter abstracts, also occur: thus, bahupā́yya protecting many, nṛpā́yya men-guarding; kuṇḍapā́yya, and purumā́yya, proper names; pūrvapā́yya first drink, mahayā́yya enjoyment; — and rasā́yya nervous, and uttamā́yya summit, contain no verbal root. Alā́yya is doubtful; also ākāyyà, which its accent refers to a different formation, along with prahāyyà (AV.: √hi) messenger, and pravāyyà (AV.), of doubtful value.
1219. आयन āyana. In the Brāhmaṇas and later, patronymics made by this suffix are not rare. They come from stems in, अ a, and have vṛddhi-strengthening of the first syllable, and accent on the final.
a. In RV., the only example of this formation is kāṇvāyana (voc.: káṇva); AV. has in metrical parts dākṣāyaṇá and the fem. rāmāyaṇī́; and āmuṣyāyaṇá son of so-and-so (516) in its prose; ÇB. has rājastambā́yana beside -bāyaná. The RV. name ukṣaṇyā́yana is of a different make, elsewhere unknown.
1220. आयी āyī. Only a very few words are made with this suffix, namely agnā́yī (agní) Agni's wife, vṛṣākapāyī wife of Vrishā́kapi; and later pūtakrātayī, and manāyī Manu's wife (but manāvī́ ÇB.).
a. They seem to be feminines of a derivative in a made with vṛddhi-increment of the final i of the primitive.
1221. इ i. Derivatives made with this suffix are patronymics from nouns in a. The accent rests on the initial syllable, which has the vṛddhi-strengthening.
a. In RV. are found half-a-dozen patronymics in i: for example, ā́gniveçi, pāúrukutsi, prā́tardani, sā́ṁvaraṇi; AV. has but one, prā́hrādi; in the Brāhmaṇas they are more common: thus, in AB., sāuyavasi, jānaṁtapi, āruṇi, jānaki, etc. A single word of other value — sā́rathi charioteer (sarátham) — is found from RV. down.
b. The words made with the so-called suffix aki — as vāiyāsaki descendant of Vyāsa — are doubtless properly derivatives in i from others in ka or aka. That the secondary suffix ika is probably made by addition of ka to a derivative in i is pointed out below (1222 j).
c. RV. has tápuṣi, apparently from tápus with a secondary i added, and the n. pr. çucantī́; bhuvantí is found in B., and jīvanti later.
1222. क ka. This is doubtless originally one of the class of suffixes forming adjectives of appurtenance. And
