ketidak-...-an
Negated Abstract Nouns
The ketidak-...-an pattern makes an abstract noun from a negated quality or state. English may use un-, in- or a phrase, but there is no fixed one-to-one affix translation. Forms such as ketidakadilan and ketidakpuasan occur in standard Indonesian, including news, professional and academic contexts.
How It Works
In Indonesian, while you can describe something as 'not fair' using tidak adil, you need a specific noun form to talk about the concept of 'injustice' itself. This is where ketidak-...-an is used.
1. Usage and Register
Many words in this pattern are common in formal and abstract discussion, but their use is not confined to formal settings. You will encounter it frequently in news reports, legal documents, and academic essays. In casual conversation, Indonesians usually prefer simpler phrases. For example, instead of saying ketidaksenangan (displeasure), a speaker would likely just say saya nggak suka (I don't like it).
2. Morphological Structure
The pattern attaches primarily to adjectives and stative verbs. As is standard for the ke-...-an circumfix, there are no nasalization changes to the root word. Write the complete derived noun as one word: ketidakadilan, not ke tidak adil an. In Indonesian grammar, whenever a circumfix wraps around a phrase with a space, the space is deleted.
- adil (fair) → ketidakadilan (injustice)
- pasti (certain) → ketidakpastian (uncertainty)
- puas (satisfied) → ketidakpuasan (dissatisfaction)
- hadir (present) → ketidakhadiran (absence)
- tahu (know) → ketidaktahuan (ignorance)
3. Complex Bases
This pattern can also be applied to complex bases that already contain other affixes, such as ber-, se-, or ter-. In these cases, the entire prefixed word acts as the base for the negation.
- berdaya (powerful/capable) → ketidakberdayaan (helplessness)
- seimbang (balanced) → ketidakseimbangan (imbalance)
- terbatas (limited) → ketidakterbatasan (boundlessness/infinity)
- teratur (organized) → ketidakteraturan (irregularity/disorder)
4. Constraints
The underlying phrase normally uses tidak with a quality or verbal state. Ordinary noun-identity negation uses bukan, so do not mechanically substitute it into established ketidak-...-an words. Productive word formation still depends on meaning and actual usage: a conceivable color or size contrast is not automatically forbidden, but an unfamiliar coinage needs a clear context. Learn common words first rather than assuming every not-X phrase has an equally ordinary noun.
Examples (5)
- Ketidakpastian ekonomi membuat banyak orang khawatir.
Economic uncertainty makes many people worried.
Word by Word: Uncertainty economy make many person worried.
Here, 'ketidakpastian' (uncertainty) acts as the subject of the sentence, formed from the adjective 'pasti' (certain).
- Mereka berjuang melawan ketidakadilan di tempat kerja.
They are fighting against injustice in the workplace.
Word by Word: They struggle against injustice in place work.
'Ketidakadilan' is the noun form of 'tidak adil' (not fair), representing the abstract concept of injustice.
- Survei itu menunjukkan tingkat ketidakpuasan yang tinggi.
The survey showed a high level of dissatisfaction.
Word by Word: Survey that show level dissatisfaction which high.
Ketidakpuasan is formed from puas, meaning satisfied, and names a state of not being satisfied.
- Ketidakmampuan untuk membayar utang adalah masalah besar.
The inability to pay debts is a big problem.
Word by Word: Inability for to-pay debt is problem big.
'Ketidakmampuan' (inability) comes from 'mampu' (capable/able).
- Ketidakhadiran manajer menyebabkan rapat ditunda.
The manager's absence caused the meeting to be postponed.
Word by Word: Absence manager cause meeting postponed.
'Ketidakhadiran' (absence) is formed from 'hadir' (present) and is a very common formal noun.
Common Mistakes
Using the casual negator 'nggak' inside the circumfix.
kenggakadilanketidakadilanThe established standard noun is ketidakadilan, built on tidak adil. Kenggakadilan is not that standard form. Informal creative formations are a different matter; the standard spelling does not mean the noun can only be used in formal settings.
Forgetting the suffix '-an'.
ketidakadilketidakadilanThe circumfix must be complete (both 'ke-' and '-an') to function as a noun. Without the suffix, the word is incomplete.
Using 'bukan' instead of 'tidak'.
kebukanadilanketidakadilanEven though 'bukan' is used to negate nouns, this specific morphological pattern requires 'tidak' because it negates the underlying adjective before turning the whole phrase into a noun.
How It Connects
Learn This First
To understand 'ketidak-...-an', you first need to know how 'tidak' negates qualities and how the 'ke-...-an' circumfix turns roots into abstract nouns. This pattern combines those two concepts to package the 'lack of' or 'opposite of' a specific state.

The 'tidak' component is the core negator used within this circumfix to indicate the absence or opposite of a quality.
