Google Wants To Be Your Dictionary

From now on, Google's word search results will include synonyms, sample sentences, and some description of the word's etymology. But word scholars will point out that Google's not necessarily making it clear where it's sourcing this information from, and that it thus risks becoming an incorrect de facto source of "truth" on some words' meanings. That's important when the origins and even correct uses of some words are disputed. The move may also be challenged by well-known dictionary brands, many of which have online portals that are now rendered less useful by Google.
