What you will learn

  1. The instrumental singular profile Instrumental relates an entity to an action or state as means, companion, role, property, or spatial reference.
  2. Masculine and neuter: -ым and -им The same forms seen in dative plural now agree with a singular masculine or neuter head.
  3. Feminine: -ой/-ей and -ою/-ею The shorter forms dominate neutral modern prose; the longer variants are grammatical but stylistically marked or rhythmically motivated.
  4. Means and instrument A means used to perform an action commonly appears in instrumental without a preposition.
  5. Accompaniment with с С + instrumental expresses accompaniment, association, mixture, or a feature possessed together with its bearer.
  6. Role, profession, and resulting state After быть in non-present tenses, стать, явля́ться, and several role constructions, instrumental presents a role, classification, or attained state.
  7. Spatial position Над, под, пе́ред, за, and ме́жду commonly take instrumental for stable position relative to a landmark.
  8. Direction versus position With под, за, and certain spatial frames, accusative marks a directed endpoint while instrumental marks resulting or stable position.
  9. Syncretism and whole-phrase analysis Instrumental singular masculine/neuter adjectives equal dative plural adjectives; feminine forms overlap several other oblique cases.
  10. Instrumental singular assessment Build the form, name the relationship, and distinguish direction from position.
