The Lexicon brings together lexical material from a wide range of published and non-published sources to create an extensive compilation of the vocabulary of Fulfulde as it is spoken in that part of central Mali known as Masina (in Fulfulde, Maasina). The Lexicon is intended primarily for non-Fulfulde speakers who are learning the language at the intermediate or advanced levels and who need access to a comprehensive reference source on Fulfulde vocabulary. Scholars, development workers, and others whose research or fieldwork involves use of the Fulfulde of Masina may find it helpful as well in clarifying nuances of meaning and standardized spelling for the less familiar terms they might encounter. It is also intended that the present work, beyond the matter of organizing vocabulary, will contribute significantly to the expanding lexicographical and linguistic investigations of Fulfulde.
