Google Web Definitions is a Google Search feature that allows users to instantly find definitions of words, phrases, and acronyms harvested directly from the internet or authoritative dictionary partners. Depending on how it is triggered, it either pulls crowd-sourced explanations found across the web or displays a highly detailed, licensed dictionary entry at the very top of your search results. How to Trigger Web Definitions
The “Define:” Operator: Typing define:[word] (e.g., define:serandite) forces Google to pull a comprehensive list of definitions it has extracted from varying web pages and online glossaries.
Natural Queries: Searching simple phrases like “what is [word]” or “[word] definition” automatically generates a dedicated dictionary card. Sourcing the Data
Oxford Languages Partnership: For standard dictionary terms, Google officially licenses its data from Oxford Languages. This provides authoritative meanings, parts of speech, and standard phonetic spellings.
Web Crawling (Google Glossary): For slang, highly technical jargon, specific acronyms, or newer pop-culture words, Google uses its automated web crawlers. The algorithm scans text across billions of public websites, identifies phrases structured as definitions, and extracts them to present as a “Web Definition”.
