"Nglish" includes a comprehensive Spanish-English dictionary with hundreds of thousands of example sentences in English, synonyms, and audio pronunciations by native speakers. Word and sentence translation is available from Spanish to English and English to Spanish. Automatic language detection makes translation fast and easy, with one single search box for both languages.

The interactive app for Android features quizzes and flashcards to help users expand their English vocabulary, while tracking progress through multiple levels. Nglish users can save words to personal word lists, accessible online and from any device, to study at their own pace.

"Nglish was designed specifically for Spanish speakers who want to learn American English in an ongoing way and in digestible bites," says Merriam-Webster, President John M. Morse. "We are pleased to offer our users high-quality dictionary content and engaging features, all in a personalized learning environment."

Additional features include Word of the Day, autocomplete in both languages, and a built-in review cycle that automatically saves quiz errors and dictionary look-ups for further practice.
