Kriol has two general invariable negative particles, no(mo) and neva. In certain contexts, specific negative auxiliaries are used – or rather, they are words such as din 'didn't' and kan 'can't' that are derived from English auxiliaries, but as they do not co-occur with TAM marking, it is unclear whether they should be considered as auxiliaries or particles in Kriol.
