Impersonal Expressions with 'Да' Clauses

Grammar Rule in 30 Seconds

Use impersonal expressions to state facts, needs, or possibilities without a specific subject by using a fixed phrase followed by 'да'.

  • The main expression stays in the 3rd person singular: 'Трябва да' (Must), 'Може да' (Can).
  • The verb after 'да' must conjugate to match the person: 'Трябва да уча' (I must study).
  • Adjectives in these phrases are always neuter: 'Важно е да...' (It is important to...).
  • Negation is formed by placing 'не' before the impersonal verb: 'Не трябва да...'

Perguntas frequentes (6)

In modern Bulgarian, 'трябва' is almost exclusively impersonal. In very old or poetic texts, you might see it conjugated, but for daily life, keep it as `трябва`.

`Мога да` means 'I am physically/mentally able to', while `Може да` means 'It is possible that'.

Bulgarian requires the verb 'to be' (`е`) in these constructions, unlike Russian where it is often omitted.

Use the past impersonal form: `Трябваше да...` followed by the conjugated verb.

Yes, in these impersonal constructions, `да` acts as the bridge between the impersonal head and the action.

Absolutely. Phrases like `Следва да се отбележи` (It should be noted) are very common in formal Bulgarian.
