di- (Jawi spelling before consonant-initial stems د-, Jawi spelling before vowel-initial stems دأ-)

1. (third person) Patient focus or passive voice marker of a verb.

   ‎di- + ‎buka (“to open”) → ‎dibuka (“was opened”)

   Pintu itu dibuka (oleh) ayah.

   That door was opened by dad.

• According to the DBP's prescriptive grammar, this prefix is to be exclusively used in the third person.
  • Patient focus sentences in the first and second persons are formed by following the subject of a sentence with the stem form of a verb.
  • The difference mentioned above is as so:
    • Third person

      Makanan itu ditelan (oleh) dia.

      That food was swallowed by him/her.

    • First/Second person

      Aku/Kamu telan makanan itu.

      That food was swallowed by me/you.

  • The first/second person form of the so-called "patient focus" or "passive voice" sentence is regularly used in informal or everyday speech with an "agent focus" or "active voice" meaning so the example first/second person sentence above can be interpreted as so:

    Aku/Kamu telan makanan itu.

    I/You swallowed that food.

• 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.

2. without, -less, de-, a-, negative prefix

   Synonyms: af-, an-, dis-

   ‎di- + ‎paid (“pause, respite”) → ‎di-baid (“ceaseless, incessant”)

   ‎di- + ‎swydd (“job, office”) + ‎-o → ‎diswyddo (“dismiss, discharge, sack, make redundant”)

The negative prefix di- indicates a lack of something and is most often attached to a noun in a similar manner to English -less, e.g. dienw (“anonymous, nameless”), di-waith (“unemployed (“workless”)”), diobaith (“hopeless”). In contrast, af- and an- simply denote the negative form of the following root rather than the lack of it.
