To make this website easier to read, pages with the Macmillan Double-Click Dictionary logo allow you to search for a word in the Macmillan Online Dictionary simply by double-clicking on a word on the page.
When you double-click on a word, a link appears allowing you to open the Macmillan Dictionary. From here, you are taken to the entry for that word. If there are two or more entries for that word, you are presented with a list from which you can choose the appropriate one.
If you want to look up words not on this website, you can do this at Macmillan Dictionaries Online.
