- īṣad iva — just a little
- kiṃcid iva — just a little bit; and after a negation e.g.
- na cirād iva — very soon
- (as a particle) connected vaguely, and somewhat pleonastically, with an interrogative pronoun or adverb, e.g.

In the pada texts of the Rigveda, Yajurveda, and Atharvaveda, and by native grammarians, iva is considered to be enclitic, and therefore compounded with the word after which it stands.
