Compound Words (Сложни думи)
Grammar Rule in 30 Seconds
Compound words combine two or more roots into one unit, usually linked by the vowels 'o' or 'e'.
- Use connecting vowels -о- or -е- to join roots, like 'водолаз' (water + dive).
- Hyphenate words where both parts retain independent identity, like 'кандидат-студент'.
- Write as one word when the parts merge into a single concept, like 'правопис'.
