A1 Case System 1 min read سهل

Grammar Rule in 30 Seconds

The Prepositional case tells us WHERE something is, usually by adding an '-е' to the end of the noun.

  • Use it to answer the question 'Where?' (Где?). Example: В парке (In the park).
  • Most masculine and neuter nouns add '-е'. Example: В доме (In the house).
  • Use it after prepositions 'в' (in) or 'на' (on/at). Example: На столе (On the table).
в/на + Noun + е = Location
