Grammar Rule in 30 Seconds

Abstract nouns in Bulgarian are formed by adding specific suffixes like -ост, -ство, and -ние to adjectives, nouns, or verbs.

  • Add -ост to adjectives to describe qualities (e.g., млад → младост).
  • Use -ство for states or collectives (e.g., роб → робство).
  • Apply -ние to verbal stems for actions or results (e.g., движа → движение).
Adjective/Verb + 🧩 (-ост/-ство/-ние) = 🧠 Abstract Concept
