Why Russian is difficult
Russian's six-case system and aspectual verb pairs require learners to encode grammatical information that English leaves implicit — making it one of the most structurally demanding languages for English speakers.
The grammar concepts that trip learners up
Grammario shows all of these in context, on every sentence you analyze.
Six-case system
Nominative, genitive, dative, accusative, instrumental, prepositional — Russian uses all six actively and endings change for every declension class.
Verbal aspect (perfective vs imperfective)
Every Russian verb comes in an aspect pair. The choice of aspect changes whether an action is completed, ongoing, or habitual — a distinction English doesn't grammaticalize.
Free word order
Russian word order is flexible and conveys information structure, not grammatical roles. Cases handle roles. Grammario's dependency graph shows the structure regardless of order.
Short-form adjectives
Russian adjectives have long and short forms used in different syntactic positions. Grammario tags which form is used and why.
