Tokpisin adjectives can be either attributive or non-attributive. The attributive type is marked by the attributive morpheme -pela; the non-attributive is unmarked. Semantically, the attributive form qualifies the noun; it attributes characteristics about the noun, while the non-attributive form states the being; the status of the noun. Syntactically, the attributive precedes the noun, while the non-attributive follows the noun. A few adjective forms like "liklik", and "nogut", are considered "non-stabilized forms" (Paradigms have been designed to use to explain some of these linguistics phenomena). Tokpisin has some of these variations still exists. Many of these variations are acceptable and are variously marked by the cognition of the speaker of the time about the noun. When someone says "nogutpela tok", the person is attributive in his thought. When he says "nogut tok" the person is non-attributive. Many non-attributive forms of Tokpisin are compound words now and must not be taken literally. For example: "tok nogut" 'swear - using bad language'; "tok i nogut" 'unacceptable message'; "tokim nogut" 'improperly said'; "nogut tok" 'bad words'.
