Questions & Answers about Субтитры слишком мелкие.
In Russian, the verb to be is usually omitted in the present tense.
So:
- Субтитры слишком мелкие. = The subtitles are too small.
But in the past or future, forms of быть do appear:
- Субтитры были слишком мелкими. = The subtitles were too small.
- Субтитры будут слишком мелкими. = The subtitles will be too small.
So the missing are is completely normal.
Because субтитры is plural, and the adjective has to agree with it.
Agreement here is:
- субтитр → singular
- субтитры → plural
So:
- Субтитр слишком мелкий. = The subtitle is too small.
- Субтитры слишком мелкие. = The subtitles are too small.
Russian adjectives change form to match the noun in number, and often also in gender and case.
