The semi-bilingual dictionary is a modern, innovative language learning tool, designed explicitly for non-English speakers. Its main core, consisting of the headword, its part of speech, definition, example of usage, and special notes, is all in English. In addition, each meaning of the headword has a brief translation in the learner's native language. The result is an English-English-native-language dictionary. Most semi-bilingual versions include also a reverse native-language-to-English section.

The combination of an English-in-English dictionary with translation is a significant step forward in learners' dictionaries, and has influenced the concept of lexicography for students of foreign languages. By providing a brief equivalent in the language of the learner, the dictionary incorporates the useful features of both monolingual and bilingual dictionaries, while avoiding their drawbacks. The learner can immerse in the English language, with active support from the mother tongue. In this way the dictionary user is encouraged to read the information in English, whereas the translation serves to provide psychological reassurance, to reinforce understanding, and to correct misunderstanding when it arises.

As part of its user-friendly approach, the semi-bilingual dictionary is visually clear and attractive. The letters are large, the text is uncrowded, and the page layout is spacious. Each meaning of every entry, sub-entry, derivative, idiom, and expression begins on a new line. This makes it easy to find, read, and use any component of the entry.

The semi-bilingual dictionary is suitable for independent learning, whether in school or at home. It aids the user in daily encounters with the English language, on computer, TV, etc. Using the dictionary as a dynamic learning tool also develops general referencing skills – how to search for information efficiently and use it productively, ie, interactive data accessing and processing.

This lexicographic concept is effective also with electronic media. The features of the semi-bilingual dictionary make the acquisition of English as the language of international communication more easy, fun, and fulfilling. This is truly a learner-friendly dictionary.
