Oxford Learner’s Dictionaries

Oxford Learner’s Dictionaries brings together seven dictionary and grammar reference titles, with web, mobile and API access. The full A–Z content of the Oxford Advanced Learner’s Dictionary and Oxford Advanced American Dictionary is available free online. Word lists include the Oxford 3000, Oxford 5000 and Oxford Phrase List, aligned to the Common European Framework of Reference for Languages. Learn & Practise Grammar offers free explanations and interactive exercises in beta. OALD Premium adds iSpeaker, iWriter, My Word Lists, downloadable resources and ad-free OALD and OAAD pages. The Oxford Learner’s Dictionary of Academic English includes 50,000 examples and is integrated with the OPAL academic vocabulary list. The API supports 35 languages and six programming languages, with search filters, sentence data, words and inflections endpoints; its free sandbox trial includes 500 calls. App access has a free 3-day trial. OALD10 app access costs $3.99 a month, $9.99 a year or $29.99, paid once for four years. iWriter and iSpeaker do not run in Internet Explorer, and double-click lookup is unavailable on mobile devices.

Oxford Learner’s Dictionaries offers free reference content alongside premium app features and a developer API. Check the browser and mobile limitations if those lookup tools matter to you.

The Oxford Advanced Learner’s Dictionary is designed for advanced-level learners of British or American English. The collection also suits learners seeking grammar resources and developers needing dictionary API access.

Oxford Learner’s Dictionaries is a collection of English dictionaries and grammar references with free online access to two core titles. It is best suited to advanced learners of British or American English who want examples, pronunciation and vocabulary-study tools. The free web dictionaries are substantial; app access and several premium study features come at a cost.

Overview

The Oxford Advanced Learner’s Dictionary and Oxford Advanced American Dictionary provide their full A–Z content online for free, including audio pronunciation, usage examples and translation lookup. That makes the site useful for regular reference without an app subscription. The wider collection adds academic English and grammar resources, while the premium app is a separate option for learners who want its additional study tools and offline access.

Key features

Reference and vocabulary study

Seven dictionary and grammar titles give the collection more range than a single general dictionary. The Oxford 3000, Oxford 5000 and Oxford Phrase List are aligned to the Common European Framework of Reference for Languages, helping learners focus on vocabulary associated with language-learning levels. The Oxford Learner’s Dictionary of Academic English includes 50,000 examples and integrates the OPAL academic vocabulary list, making it the more relevant choice for readers developing academic English.

Grammar and premium tools

Learn & Practise Grammar pairs explanations with interactive exercises at no cost. Its beta status makes it a useful supplement, but a less certain choice as the backbone of a structured course. OALD Premium adds iSpeaker, iWriter, My Word Lists, downloadable resources and ad-free pages for OALD and OAAD. These features suit learners who will make use of writing and vocabulary tools; occasional lookups can rely on the free dictionaries instead.

The Oxford Dictionaries API supports 35 languages and six programming languages, with search filters, sentence data, words and inflections endpoints. Its sandbox trial includes 500 calls, giving developers a bounded way to explore the API before deciding whether it fits an integration.

Pricing

The free online plan costs nothing and includes the full A–Z OALD and OAAD, Text Checker, word lists and sample resources. It is the strongest starting point for readers who primarily need web reference, but it does not include the app’s unlimited dictionary access.

The Free 3-day trial costs nothing and provides three days of app access. For longer use, One-month access to OALD10 app costs $3.99 a month, One-year access to OALD10 app costs $9.99 a year, and Four-years access to OALD10 costs $29.99, paid once. Each paid option provides unlimited dictionary access for its stated period; the shorter plan suits a brief need, while the longer terms reduce how often access must be renewed. Premium web study tools are described separately as OALD Premium.

Platforms

Oxford supports Android, iOS, macOS, web and API access. Offline access is available, which makes the mobile app more useful when a connection is unavailable. On mobile devices, however, double-click lookup of unknown words inside entries is unavailable. iWriter and iSpeaker do not run in Internet Explorer, so users relying on that browser should not count on those tools.

Who it's for

Advanced learners choosing between British and American English will get the clearest fit, especially if they value examples and pronunciation as much as definitions. Academic readers can draw on the academic dictionary’s examples and OPAL integration, while developers can assess the API through its 500-call sandbox. It is less suitable for learners who depend on mobile double-click lookup or want the premium writing and speaking tools without paying.

Pros and cons

• Pros: Full A–Z access to two core dictionaries is free online, so routine reference does not require app access.
• Pros: CEFR-aligned word lists, audio, examples and academic vocabulary support several specific study needs.
• Pros: The API’s language coverage and endpoints give developers multiple ways to retrieve dictionary data.
• Cons: The useful iWriter and iSpeaker tools are browser-limited in Internet Explorer, and mobile entries lack double-click lookup.
• Cons: Grammar practice remains in beta, while OALD Premium tools require a paid option.

Alternatives

Cambridge Dictionary is a natural alternative for readers who want free online dictionaries plus word lists and quizzes, with Android, iOS, web and API access. Linguee is the simpler free option for private and business use across Android, iOS and web. Choose Pleco Chinese Dictionary for Chinese lookup instead: its free version includes basic search, handwriting and included dictionaries, with limited reader, audio and flashcards. Merriam-Webster Dictionary is another free app option, with ads and offline dictionary and thesaurus access; its premium version removes ads. dict.cc offers free browser use for private and business purposes, and is a straightforward choice for readers who want a web dictionary. ABBYY Lingvo is another freemium dictionary option across Android, iOS, macOS and Windows. MDBG Chinese Dictionary offers a free online dictionary and learning tools, making it an alternative for Chinese study. PONS Dictionary provides ad-supported online access and a free-to-download translation app with in-app purchases. See more options in Online Dictionaries.

Verdict

Oxford Learner’s Dictionaries is the right choice for advanced English learners who want substantial free reference content and can benefit from its focused vocabulary resources. Its strongest reason to choose is the combination of two full free online dictionaries with deeper academic and learner-oriented materials. Look elsewhere if mobile double-click lookup is essential, or if you need premium study tools without an added cost.
