Where this information comes from

Wiktionary data was expanded into structured fields by Wiktextract. Matching Princeton WordNet definitions and semantic relationships, plus CMUdict ARPABET pronunciations, are merged into this same canonical word page.

Wiktionary text is credited to English Wiktionary contributors under Creative Commons Attribution-ShareAlike 4.0. The source entry and revision history URL, legal text, and the complete attribution and reuse instructions are collected on the site-wide Sources, credits & licenses page.

Changes made: Wiktionary markup was removed and matching senses were grouped; WordNet and CMUdict evidence was merged into the canonical word page. Source quotations with separate cited works are not republished.

The page is served entirely from a local, versioned copy; opening it makes no upstream request or external navigation.
