A lexicon for Tuvaluan, a Polynesian language spoken in the Gilbert and Ellice Islands, contains two parts, a lexicon and a word finder. The lexicon has a traditional format, in which Tuvaluan words are listed alphabetically and defined in English, and in which all additional information on structure, usage, and dialect can be found. The second part is a cross-listing of all English definitions appearing in the first part with the Tuvaluan head-word under which the English word appears. Entries contain information on the dialect name, the source of borrowings, Proto-Polynesian origin, morphological structure, parts of speech, the possessive class, the non-singular form, definition, examples, scientific names for botanical and zoological entries, and references to other entries. Notes on orthography and alphabetical order precede the lexicon. The reader is cautioned that this edition is provisional, designed as a short-term working lexicon, with all information subject to change. (Author/MSE)
