Questions & Answers about Они не могут формулировать новаторские концепции.
Why use the imperfective формулировать here instead of the perfective сформулировать?
Because the sentence describes a general inability or lack of capacity to perform this action at all, rather than failing to formulate one specific concept. When expressing a general state or ability (especially after не могут), Russian strongly prefers the imperfective aspect.
What is the difference between новаторские and just новые?
Новые simply means "new," whereas новаторские specifically means "innovative" or "pioneering." It is built from the noun новатор (innovator), highlighting that these concepts break new ground, not just that they were recently created.
Why does the direct object концепции end in -и?
It is in the accusative plural form. Since концепция (concept) is an inanimate feminine noun, its accusative plural form is identical to its nominative plural, which is formed by replacing the final -я with -и.
How would we change this sentence to say they cannot formulate other concepts, using the pronoun иной from this lesson?
