Questions & Answers about Oboje su kandidati.
Here oboje means both or both of them. It refers to two people together and acts as the subject of the sentence.
So Oboje su kandidati. = Both are candidates.
Because oboje refers to two people, so the verb agrees with that plural meaning.
- su = are
- je = is
Even though oboje may look like a singular/neuter form to a learner, its meaning is plural here, so su is correct.
Because kandidati is the predicate noun after su, so it is in the nominative plural.
Compare:
- Oboje su kandidati. = Both are candidates.
- oba kandidata = both candidates
In oba kandidata, the numeral directly modifies the noun, which gives a different form. But in Oboje su kandidati, you have a full sentence with are, so kandidati is nominative plural.
