Look it up
Mac OS X 1.4 (Tiger) introduced many new features, including Widgets, small programs accessed from the Dashboard. One of these was the dictionary widget, which does just what you would think. It lets you look up a word and gives you the definition. It works very well as long as the word you want is in the Oxford American Dictionary, which the widget uses.
If the widget doesn't find the word you are looking for or if you don't have a Mac, try looking it up on OneLook®. It uses 931 dictionaries (at the time of this post) and produces a very compact list of results to look at, along with the most common definition of the word and lots of links to related and more specialized result lists. Unlike the venerable dictionary.com, OneLook® has no pop-up windows.
