Questions & Answers about Иногда слова ранят сердце.
The subject is слова and the object is сердце.
- слова – nominative plural of слово (a word). Nominative is the “dictionary form” used for the subject of the sentence.
- сердце – accusative singular of сердце (heart). Accusative is used for the direct object, the thing being affected by the action.
So the literal structure is:
(Иногда) слова (subject) ранят (verb) сердце (object).
Because сердце is a neuter, inanimate noun, and for that group the nominative and accusative singular forms are identical.
- Nominative singular: сердце
- Accusative singular: сердце
If сердце were animate (a living being), its accusative would usually match the genitive, but inanimate nouns (like objects, abstract things) often keep the nominative form in the accusative.
