Questions & Answers about Ponovna upotreba i reciklaža su važne.
Why is su used here?
Su is the present-tense form of biti (to be) for they are.
So:
- je = is
- su = are
Because the subject is made of two things — ponovna upotreba and reciklaža — Serbian uses the plural verb: su.
So structurally, this is:
- Ponovna upotreba i reciklaža = the subject
- su = are
- važne = important
Why is it važne, not važna?
Because važne is the plural feminine form of važan (important).
Both nouns in the subject are feminine singular nouns:
- upotreba = feminine
- reciklaža = feminine
When two feminine nouns are joined by i (and), the predicate goes into the plural, and the adjective agrees with that plural subject:
- singular feminine: važna
- plural feminine: važne
So:
- upotreba je važna = reuse is important
- reciklaža je važna = recycling is important
- upotreba i reciklaža su važne = reuse and recycling are important
