Dictionary.com Word FAQs
Where can I find the meaning of a word that is not in any online or printed dictionary?
You can try to deduce the meaning of a very new term, an obscure term, slang, or technical vocabulary in a number of ways. On the computer, you can type the term (in quotation marks if it consists of more than one word) into a search engine and see what the results bring. In some search engines, you can try tricks like "define: yourword," "glossary yourword" and "what does yourword mean?"
