The appearance of Lise Winer’s dictionary is the single most important event in the study of language in Trinidad and Tobago since 1869. In that year, John Jacob Thomas published his classic, The theory and practice of Creole grammar. That volume provided the first attempt at a comprehensive grammatical description of a French lexicon Creole anywhere in the world. It made the study of language behaviour in Trinidad and Tobago an area of referential attention for scholars in the field of Creole linguistics.
