Content features

• Headwords: Tens of thousands of entries covering common and many less common words, including variant spellings and common idioms.
• Pronunciation: IPA‑style respelling or Merriam‑Webster’s pronunciation system for each headword, with stress marks and syllabification.
• Etymologies: Brief word‑history notes tracing roots (e.g., Old English, Latin, Greek, French), often concise compared with unabridged dictionaries.
• Part of speech labels: Clear grammatical categories (noun, verb, adjective, adverb, etc.).
• Definitions: Multiple numbered senses arranged from most to least common; usage labels (archaic, dialect, informal, slang).
• Usage notes: Short essays or labels where contested or confusing usage exists (e.g., affect/effect, less/fewer). These are aimed at practical correctness rather than theoretical prescriptivism.
• Examples: Select illustrative quotations or example phrases showing typical usage.
• Variant forms and inflections: Plural, past tense forms, and common derivatives.
• Appendix material: Often brief lists or appendices for pronunciation symbols, foreign words and phrases, weights and measures, common abbreviations, and similar practical reference items.
• Illustrations/diagrams: Minimal or none — MWCD focuses on text rather than pictorial illustration.
