The Oxford Thesaurus of English, Second Edition (OTE, オックスフォード類語辞典), is a comprehensive guide to synonyms, and this Enfour app includes its complete text along with the extensive reading and reference material that accompanies the core entries.

It helps writers, students, and learners of English find a more precise or more varied word. Searches update as you type, wildcard searches help with uncertain spellings and word puzzles, and the three-way cross-referencing search finds words wherever they appear. Hyperlinks connect entries with each other and with the appendices.

The app runs on Enfour’s UniDict® engine, which supports round-trip searches from other compatible apps and dictionaries, including the Oxford Dictionary of English. Bookmarks with notes, automatic history, and an AI-boosted anagram generator are built in, and accessibility options include a dyslexia-friendly mode and VoiceOver support. Everything works offline.
