About Merriam-Webster Dictionary
Merriam-Webster Dictionary is the mobile edition of the long-running American dictionary. It looks up definitions, pronunciations, example sentences and synonyms from Merriam-Webster's English references, and the store listings say the content is continuously updated with new words.
Beyond lookups, the app offers voice search, a word of the day, word games and quizzes, and a thesaurus. The App Store listing mentions iPhone, iPad and Apple Watch support, and the most recent iOS update added 1,400 new words and definitions. A search history and saved word lists help with review.
It suits students, writers and anyone who wants a trustworthy American English reference on a phone. The app is free to download and carries ads. The Google Play listing also shows in-app purchases, which are used to remove ads or unlock extra features. A basic lookup does not require an account. It is a good everyday companion for checking spelling, meaning and usage while reading or writing on a phone or tablet.
Handy for quick lookups, though the ad placement can feel intrusive on small screens. The ad-free upgrade is worth considering if you use it daily.
