Infinitive + vacibdir

Vacibdir Obligation

Level 3

The pattern [Infinitive] + vacibdir is used to state that an action is important or necessary. It is the standard way to say 'It is important to...' or 'It is essential that...' in Azerbaijani.

How It Works

The vacibdir + infinitive pattern is a nominal predicate construction. Unlike the vacib mood (-malı/-məli), which is a direct verb conjugation, vacibdir describes the quality of the action itself.

1. General Statements:
When speaking about a general rule or advice, use the standard infinitive form:

  • Oxumaq vacibdir. (Reading is important.)

2. Specific Subjects:
To specify who must perform the action, the subject is put in the genitive case and the infinitive takes a possessive suffix.

Phonetic Note: When adding a possessive suffix to the infinitive, the final consonant changes: -maq becomes -mağ- and -mək becomes -məy- (e.g., gəlmək + -in = gəlməyin).

  • Sənin gəlməyin vacibdir. (It is important that you come / Your coming is important.)
  • Onun oxumağı vacibdir. (It is important that he/she reads.)

3. Tense and Negation:
To change the meaning, you can modify the copula:

  • Negative: Use deyil (e.g., vacib deyil - it is not important).
  • Past: Use the past copula idi (e.g., vacib idi - it was important).

Examples (5)

  1. Qaydaları bilmək vacibdir.

    It is important to know the rules.

    Word by Word: Rules to-know important-is.

    A general statement using the standard infinitive form.

  2. Sizin bu sənədi imzalamağınız vacibdir.

    It is important that you sign this document.

    Word by Word: Your this document signing-your important-is.

    Here, the specific subject 'you' (formal) requires the genitive case and a possessive suffix on the infinitive.

  3. Düz danışmaq hər zaman vacibdir.

    It is always important to speak the truth.

    Word by Word: Straight to-speak every time important-is.

    Used to express a moral duty or general principle.

  4. Onun vaxtında gəlməsi vacib idi.

    It was important for him/her to come on time.

    Word by Word: His/her in-time coming-his/her important was.

    Demonstrates the use of the past tense with 'idi'.

  5. İndi getmək vacib deyil.

    It is not important to go now.

    Word by Word: Now to-go important not-is.

    Demonstrates negation using 'deyil'.

Common Mistakes

  • Using the nominative case for specific subjects instead of the genitive.

    Sən getmək vacibdir.
    Sənin getməyin vacibdir.

    When a specific person is the subject of the importance, the person must be in the genitive case (Sənin) and the verb must have a possessive suffix (-in).

  • Redundancy by combining the -malı suffix with vacibdir.

    Gəlməli vacibdir.
    Gəlmək vacibdir.

    Using the -malı form directly with vacibdir is redundant, because vacibdir already says it is necessary. Choose one of them.
