Questions & Answers about Мой адвокат настоял на этом решении.
Why do we use the prepositional case for "этом решении" instead of the accusative?
In Russian, verbs of insistence like настоять (to insist) always take the preposition на followed by the Prepositional case. This is a fixed rule for verbs in this category, unlike verbs of physical direction which take на + Accusative.
Why is the word "решении" spelled with a double "и" at the end instead of the standard prepositional "-е"?
Neuter nouns that end in -ие in the nominative case, like решение (decision), belong to a special declension group. In the Prepositional case, their ending changes to -ии rather than the standard -е.
We are using the perfective verb "настоял" here. How would the meaning change if we used the imperfective "настаивал"?
Using the perfective настоял focuses on the successful result: the lawyer insisted, and the decision was finalized. If you used the imperfective настаивал, it would mean he was actively demanding it, but the final outcome would be unknown or still ongoing.
