Breakdown of Pokrivenost mrežom i brzina interneta su važne.
Questions & Answers about Pokrivenost mrežom i brzina interneta su važne.
Because the subject contains two things joined by i:
- pokrivenost mrežom
- brzina interneta
Together, they form a plural subject, so Croatian uses plural agreement:
- su = are
- važne = important in the plural
If you mentioned only one item, you would use singular:
- Pokrivenost mrežom je važna.
- Brzina interneta je važna.
Both nouns in the subject are feminine:
- pokrivenost = feminine
- brzina = feminine
So the predicate adjective važan must agree with them in gender and number. Since there are two feminine nouns, the form is važne.
A useful comparison:
- masculine plural: važni
- feminine plural: važne
- neuter plural: važna
If the nouns were of mixed gender, Croatian often uses masculine plural as the default.
