About Usage Dictionary

Usage Dictionary is a free online reference for American English usage, covering grammar, punctuation, spelling, word choice, and style.

Entries explain distinctions between commonly confused words, address questions of usage, and provide recommendations for standard English, supported by examples that illustrate the guidance.

Usage Dictionary was created and is edited by Eric Hertz, a copy editor. The dictionary is intended for writers, editors, students, and anyone seeking clear guidance on English usage.
