According to the editors, this dictionary "contains words and phrases likely to be met in reading and everyday life, including a number of slang, informal, and technical words and phrases." Many proper nouns, common foreign words, and abbreviations are defined, too. I suggest its purchase to university students for classroom use because this dictionary is small enough to be carried in a backpack. Students of English as a foreign language find its pronunciation guides easy to use. Others find it quite handy to keep nearby, in offices and homes, as a quick reference when writing or reading.
Highly recommended!
I am not a native speaker of North American English, and as such have relied extensively on OAD for all the help I can get -- particularly in the area of pronunciation. The system is uniquely logical, makes a lot of sense and is easy to master. I've recommended it to so many who are in my position. I would be thoroughly disappointed if I learned that the publication had been discontinued.
