Whitaker's Words Latin Dictionary
Latin dictionary and grammar aid: Latin to English, English to Latin.
Written in the Ada programming language, William Whitaker's Words Latin dictionary provides definitions and grammatical analysis of words found in Latin texts. It can deduce the dictionary form of a word based on the form actually found in a text. It can handle Latin words, phrases, or whole files. The dictionary contains some 39000 entries, as would be counted in an ordinary dictionary. This may generate many hundreds of thousands of 'words' that one can construct over all the declensions and conjugations. A few hundred prefixes and suffixes further enlarge the range. These will generate tens of thousands of additional words. An English-to-Latin feature uses the same data to provide the Latin equivalent of an English word. -

Lingueez - Vocabulary Builder
Collect vocabulary from anywhere, organize, and master it.
Lingueez helps you build vocabulary across languages and actually remember it. Add a word the moment you meet it — from any app, with a global shortcut — and Lingueez looks up its definition and translation for you. It then turns your personal word list into spaced-repetition flashcards that resurface each word right before you'd forget it, so your study time goes where it's needed most. And when recognizing a word is no longer enough, the quiz asks you to pick the right answer — or type it out yourself, in either direction. Beyond flashcards, Lingueez reads your words aloud with natural text-to-speech and generates short reading passages built from the vocabulary you're learning, so you see every word in real context. Your library is yours: everything works offline, with no account required. Sign in only if you want your words and progress synced across devices. Free and open source. No ads, no subscription. -
