This book is part of the Island Alphabet Books series, which features languages and childrens' artwork from the U.S.-affiliated Pacific. Each hardcover book contains the complete alphabet for the language, four or five examples for each letter, and a word list with English translations. The series was co-published with Pacific Resources for Education and Learning, a non-profit corporation that works collaboratively with school systems to enhance education across the Pacific.

Carolinian is a member of the Trukic subgroup of the Micronesian group of Oceanic languages. This is the first English dictionary of the three Carolinian dialects spoken by descendants of voyagers who migrated from atolls in the Central Caroline Islands to Saipan in the Northern Mariana Islands. This dictionary provides English definitions for almost 7,000 Carolinian entries and an English-Carolinian finder list. A special effort was made to include culturally important words, particularly those related to sailing, fishing, cooking, house building, traditional religion, and family structure. With this work, the compilers also establish an acceptable standard writing system with which to record the Carolinian language.
