Collins Dictionary review
A broad free dictionary for definitions, language tools, translations, and offline mobile lookup.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Collins Dictionary is an online reference service for people who need everyday definitions, translations, pronunciations, examples, and language-learning tools. It covers British and American English, with specialized subject definitions, synonyms, quotations, word lists, grammar resources, conjugation tools, and thesaurus content. The service suits students, writers, language learners, and general readers who want a broad dictionary available on the web and through apps.
Its strongest point is breadth within language reference. Audio and video pronunciations support listening and speaking, while example sentences from the Collins corpus show words in context. Users can look up translations in 27 languages, use bilingual dictionaries, and work with spelling suggestions, wildcard search, and search within entries. Bookmarks, history, and favorites support repeated lookups. Official applications cover iOS, Android, and macOS, with offline dictionary access available in the mobile apps.
The published offering combines a free online dictionary with paid mobile and desktop dictionary applications. The free service includes definitions, translations, pronunciations, examples, and language tools, while the separate applications create additional options for people who want installed access. Collins is a strong fit for broad, recurring reference work across English and multiple languages. Readers seeking a focused language dictionary will find substantial coverage, but those wanting a general writing workspace or a single unified app-and-web product may prefer a more narrowly integrated alternative.
