** (with consonant-initial stem) IPA: [di-]

### Prefix

di- (Jawi spelling before consonant-initial stems د-, Jawi spelling before vowel-initial stems دأ-)
* (third person) Patient focus or passive voice marker of a verb.
    ‎di- + ‎buka (“to open”) → ‎dibuka (“to be opened”)
    Pintu itu dibuka (oleh) ayah.That door was opened by dad.

#### Usage notes

* According to the DBP's prescriptive grammar, this prefix is to be exclusively used in the third person. In the first and second persons, patient focus sentences are formed by following the subject of a sentence with the stem form of a verb, demonstrated below with the verb telan (“swallow”):
** Third person patient focus:
    Makanan itu ditelan (oleh) dia.That food was swallowed by him/her.
** First/Second person patient focus:
    Makanan itu aku/kamu telan.That food was swallowed by me/you.
* When the sentence agent appears right after the verb as in "The homework was completed by Adam in three minutes.", it can optionally be preceded by the preposition oleh, so the aforementioned sentence can be translated in the two ways shown below:
    Kerja sekolah itu disiapkan Adam dalam tiga minit.
    Kerja sekolah itu disiapkan oleh Adam dalam tiga minit.That homework was completed by Adam in three minutes.
* If the sentence agent does not appear right after the verb as in "The homework was completed in three minutes by Adam.", the oleh preposition is now compulsory, as in the sentence below:
    Kerja sekolah itu disiapkan dalam tiga minit oleh Adam.That homework was completed in three minutes by Adam.

In contrast, af- and an- simply denote the negative form of the following root rather than the lack of it.
