English Collins Pro Dictionary is a collegiate-level lexicon and verb book for students and travelers, offering thousands of entries including slang, technical terms, and idiomatic expressions. We provide a rich thesaurus of synonyms and antonyms, full verb conjugations in all tenses, and the conversion of numbers to text.


No mere phrase-book or word list, this robust language tool provides a full verb book with conjugations in all tenses, and translation of numbers to text. Collins dictionaries allow users to conjugate any verb by using any form of a word (in most languages) when searching - from subjunctive to feminine plural. Flash card features allow users to create flash cards, and then review them with our gorgeous animated full-screen flashcard view.


Collins translation dictionaries have up to 250,000 entries each and require no internet connection to use. They contain more indications of use and context, and richer, fuller entries for the power user.


Collins by Ultralingua is available for English, Spanish, French, Italian, Portuguese, German, and more.
