In Dusun, expressing negation (saying "don't", “no,” “not,” or “none”) is simple once you know a few key words.
There are only a handful of negation words, but each one behaves differently depending on context and sentence structure.
🚫 Main Negation Words
amu → not / do not / no (tidak)
okon → is not / are not (bukan) -used for identity or classification
aiso → none / nothing / no one (tiada)
kada → don’t (jangan) - used for commands
mada → don’t want (tidak mau) - used for intention or refusal
Rule 1: Use amu before a pronoun and a verb/adjective
The most common negation word is amu. It is always followed by a subject pronoun (e.g. oku, ko, yau) and then the verb or adjective.
Examples:
Amu oku karati → I don't understand
Amu ko mongoi → You are not going
Amu yau nokorikot → He didn’t arrive
Rule 2: Use okon for identity or classification
Use okon when you want to negate something’s identity or label — for example, “He is not a doctor” or “That’s not your house.”
Examples:
Okon yoho → It wasn't me
Okon ko dokutur yau dih? → Isn’t he a doctor?
Okon ih diya doh walai → That is not your house
Rule 3: Use aiso to express “none” or “no one”
Use aiso when there is a complete absence of something — whether it’s people, objects, or ideas.
Examples:
Aiso tangaanak hilo → There are no children there
Aiso tulun mangakan takano → No one is eating rice
Aiso nunu doho ti → I have nothing (no possessions)
Rule 4: Use kada for “don’t” in commands
Kada is used to tell someone not to do something — just like an imperative “don’t” in English.
It works like a command and does not need a subject pronoun.
Examples:
Kada ongoi → Don’t go
Kada ihad → Don’t cry
Kada minayo → Don’t play
You’ll often hear this used in everyday speech when giving instructions or warnings, especially to children.
Rule 5: Use mada to express “don’t want”
Mada expresses a lack of desire or intention. It is usually followed by a subject and a verb.
Examples:
Mada oku → I don’t want (to)
Mada oku mangakan → I don’t want to eat
Mada is John mongoi sikul → John doesn’t want to go to school
This form is different from amu, which simply says something is not happening. Mada implies a personal choice or will.
🧭 Placement in Sentences
Negation words like amu, mada, aiso usually appear near the beginning of the clause, especially before the subject pronoun and verb.
However, in longer or compound sentences, they can appear later — but never as the last word.
Examples:
Ogumu tusin dau nga aiso walai → He is rich but has no house
Hiti oku walai sabab amu oku nokoilo haro kalas → I’m at home because I didn’t know there was class
