Below are some of the features of creole grammars:

• absence of number, gender, and case marking in nouns and adjectives;
• fairly complex systems of personal pronouns;
• invariant verb forms which are commonly either derived from the infinitive or based on the least marked finite verb form;
• absence of copula, e.g., in Hawai’ian Creole, mai sista skini ‘my sister is skinny’, yu da boss ‘you are the boss’;
