-dığını/-diyini (tamamlıq)

Factual Complement Clause

Level 4

The -dığını/-diyini suffix creates a 'that' clause in Azerbaijani. It is used when you want to state a fact as the object of another verb (e.g., 'I know that he came').

How It Works

The -dığını/-diyini complement is the standard way to form factual object clauses in Azerbaijani, in writing and in speech. It treats the subordinate clause as a proven reality (realis).

1. Construction:
The pattern follows a strict morphological order:

  • Verb Stem + -dıq/-dik/-duq/-dük (Participle)
  • + Possessive Suffix (matching the person doing the action: -ım/-im/-um/-üm, -ın/-in/-un/-ün, -ı/-i/-u/-ü, -ımız/-imiz/-umuz/-ümüz, -ınız/-iniz/-unuz/-ünüz, -ları/-ləri)
  • + -n- (Buffer consonant for 3rd person)
  • + Case Ending (Usually Accusative -ı/-i/-u/-ü, but can be Dative, Ablative, etc., depending on the main verb)

Note that the buffer consonant -n- is only used after 3rd person possessive suffixes. For all 1st and 2nd person possessives (both singular and plural), which end in a consonant (-m, -n, -z), the case ending attaches directly without a buffer (e.g., gəldiyim-i, gəldiyimiz-i).

2. Phonological Changes:
When a possessive suffix starting with a vowel is added to the -dıq/-dik suffix, the final -q changes to -ğ and -k changes to -y (e.g., oxuduq + -um + -u becomes oxuduğumu, and gəldik + -im + -i becomes gəldiyimi). However, the 3rd person plural possessive suffix (-ları/-ləri) starts with a consonant, so no mutation occurs (e.g., oxuduqlarını, gəldiklərini).

3. The 2nd vs. 3rd Person Ambiguity:
A crucial feature of this pattern is the ambiguity between the 2nd-person singular and 3rd-person singular forms across all cases (such as Accusative, Dative, Locative, and Ablative). For example, in the accusative case, both result in the exact same form: gəldiyini. For the 2nd person, it is gəldiy + in + i (participle + your + accusative). For the 3rd person, it is gəldiy + i + n + i (participle + his/her + buffer + accusative). To clarify whether it means 'that you came' or 'that he/she came', genitive pronouns (sənin vs. onun) are often required.

4. Tense Nuance:
Despite containing the -dıq element, this pattern is non-future. It can represent both past and present actions depending on the context and the main verb. For future events, the -acağını/-əcəyini pattern must be used instead.

5. Subject Case:
In formal writing, the subject of the subordinate clause usually takes the genitive case (e.g., Onun gəldiyini bilirəm).

6. Negation:
To negate the clause, place the negative suffix -ma/-mə directly after the verb stem, before the participle suffix (e.g., gəl-mə-diy-i-n-i).

Examples (6)

  1. Sənin haqlı olduğunu düşünürəm.

    I think that you are right.

    Word by Word: Your right being-your-acc I-think.

    Here, olduğunu turns the state of 'being right' into the object of the verb 'think'.

  2. Onun harada yaşadığını bilmirəm.

    I don't know where he lives.

    Word by Word: His where living-his-acc I-don't-know.

    The suffix -dığını indicates a factual location that is unknown to the speaker.

  3. Məni sevdiyini söylədi.

    He/she said that he/she loves me.

    Word by Word: Me loving-his/her-acc he/she-said.

    The verb 'sev-' (to love) is nominalized using -diyini to function as the direct object of 'söylədi' (said).

  4. Bakıya gəldiyini eşitdim.

    I heard that you came to Baku.

    Word by Word: To-Baku coming-your-acc I-heard.

    This demonstrates the past-tense interpretation of the non-future -diyini suffix.

  5. Onların bizə kömək etdiklərini gördük.

    We saw that they were helping us.

    Word by Word: Their to-us help doing-their-acc we-saw.

    The plural possessive -ləri is used within the complement clause to agree with the plural subject 'onların'.

  6. Onun gəldiyinə sevindim.

    I was glad that he came.

    Word by Word: His coming-his-dat I-rejoiced.

    While this pattern is named after its accusative form, the complement can take other cases like the dative case (-ə) when required by the main verb (like 'sevinmək').

Common Mistakes

  • Omitting the possessive suffix.

    Onun gəldiyni bilirəm.
    Onun gəldiyini bilirəm.

    You must include the possessive suffix (-i-) before the case marker (-ni). The structure is: gəl + dik + i + n + i.

  • Using -dığını for future events.

    Sabah gəldiyini bilirəm.
    Sabah gələcəyini bilirəm.

    -dığını is only for past or present facts. For future 'that' clauses, use -acağını/-əcəyini.

  • Forgetting the 'n' buffer consonant.

    Onun gəldiyii gördüm.
    Onun gəldiyini gördüm.

    When adding the accusative case to a 3rd person possessive suffix, you must use the 'n' buffer.

Learn This First

To understand the -dığını/-diyini complement, you must first be comfortable with how Azerbaijani uses possessive suffixes on verbs to create noun-like clauses. This pattern specifically functions as a direct object, so you need to understand the genitive-possessive relationship (to identify the subject of the complement) and the accusative case (to mark the clause as the object of verbs like 'know', 'say', or 'think').
