Instrument Prepositions in Romanian grammar are used to indicate a relationship between an object and an action โ that is, how an action is being performed. They help describe situations where an object is used as a tool or means to perform an action. Some common examples of instrument prepositions in Romanian are โcuโ (with), โdeโ (by, of), โpeโ (on), and โlaโ (at). These prepositions are a crucial component of Romanian grammar, part and parcel of creating context and meaning in a sentence.
