100 Words Everyone Confuses and Misuses

100 Words Everyone Confuses and Misuses (英単百：勘違いしがちな言葉100) is a practical usage guide from the editors of the American Heritage® Dictionaries. It looks at one hundred of the most commonly confused and misused words in English, the bugbears, pet peeves, and faux pas that trip up writers and speakers alike.

Each entry explains in clear language how the words should be used, and helps you tell genuine errors apart from matters of taste and style. The guidance draws on the advice of the American Heritage® Usage Panel, a group of respected writers and language experts. It is a handy companion for students, professionals, and anyone who wants to write and speak with more confidence.

Like the other titles in the series, the app includes the entire text of the book, pre-recorded pronunciations, real-time, and wildcard searches, bookmarks with notes, and automatic history. It works completely offline, and every word can be tapped to open compatible UniDict® dictionaries such as the American Heritage® Dictionaries, if installed.
