This is the 1st most frequent Romanian word.
de
The Romanian word "de" is a preposition meaning "of" or "from."
The word 'de' is used here as a preposition equivalent to 'of' in English, linking the quantity ('un kilogram') to the item ('mere,' meaning 'apples').
El a cumpărat un kilogram de mere.
He bought a kilogram of apples.
In this context, 'de' serves as part of the phrase 'de la,' which means 'from,' used to indicate the origin or source ('muncă,' meaning work).
Am vorbit despre proiectul de la muncă.
I talked about the project from work.
In this sentence, 'de' is included in the word 'departe,' acting as a prefix to form the word meaning 'far away.' It doesn't have a standalone usage here but contributes to the overall meaning of the compound word.
