Questions & Answers about Ruta je sigurna.
Because ruta is a feminine singular noun, and adjectives in Serbian must agree with the noun they describe.
So:
- masculine: siguran
- feminine: sigurna
- neuter: sigurno
Since ruta is feminine, the correct form is sigurna.
Je is the 3rd person singular present tense form of biti = to be.
So here it means is:
- Ruta = route
- je = is
- sigurna = safe
This is the normal way to make a sentence like The route is safe in Serbian.
In standard Serbian, no. You normally need je in this kind of sentence.
So:
- Ruta je sigurna. = correct
- Ruta sigurna. = not standard as a normal full sentence
Serbian often leaves out subject pronouns like ja, ti, on, but not the verb to be in a sentence like this.
