This volume serves as a comprehensive, dual-purpose reference tool designed to provide both lexical definitions and practical guidance on contemporary English usage. The authors, drawing upon the extensive linguistic resources and computer databases of the Oxford Dictionaries Department, synthesize lexicographical data with prescriptive and descriptive grammatical standards. By integrating a dictionary with a dedicated usage manual, the text aims to resolve common ambiguities in spelling, punctuation, and idiomatic expression for the modern reader.

Experts recognize this work as a reliable, foundational reference for students and professionals seeking clarity on standard English conventions. Readers frequently note the accessibility of the usage notes, which effectively bridge the gap between formal dictionary definitions and real-world application.
