Homonyms are pairs of words (sometimes three or four words) that sound alike, but have different spellings and meanings, such as "side-sighed," "bare-bear," and "seen-scene." This book has been written not only because homonyms pose a problem for many native speakers of English, but because they are also particularly troublesome for learners of English as a second language. This collection does not contain every homonym, but it does contain many of the most common ones. Mostly Homonyms is a new treatment of a traditional topic that is easy to read and use without sacrificing academic relevance. It is intended not only for anyone who wishes to ascertain the correct spelling and usage of a homonym, whether non-native learners of English or native speakers of English, but also for people who just love words.
