In each instance yajna-yajna stands in parisyllabic
relationship with a line-initial amredita in the following pada, and this in turn helps to produce parisyllabic
vertical cola in the two lines: I.
The first two of these passages represent perfect vertical parisyllabic responsions.
a), (c), and (d) are perfect responsions, the latter two also parisyllabic.
b) is the most tightly constructed tetracolon in the Rigveda, a perfect parisyllabic responsion made up of elemental ritual shouts.
c) is a four-word parisyllabic responsion with the order 1234/3214, subject and object showing inverted positions surrounding a fixed, second-position verb.
The perfect vertical parisyllabic responsive patterns of (a), (e), and (f) are also impressive, as is both the morphological and semantic identity of the non-repeated responsive words of (f) and the structural identity of (e).
The tricola typically feature two perfect or near-perfect parisyllabic responsions and a third which shows variation:
In (a) the first two padas are parisyllabic with word-forword grammatical parallelism, while the fourth shows variation in the grammatical role of its final word.
