This paper studies the meaning of fuzzy preferences under the light of intuitionistic fuzzy sets. Intuitionism is revisited and intuitionistic fuzzy preference relations are defined. A linguistic interpretation of strict and weak fuzzy preferences is then developed where indecision can be explicitly analyzed with the help of a bilattice. Uncertainty is finally examined as a measure of ignorance associated to the intensity value of the preference predicate, where some information measures are applied over its complete structure.
