To make the content of any website or blog easier to read, the Macmillan Double-Click Dictionary feature allows you to search for a word in Macmillan Dictionary simply by double-clicking on the word on the page.
When you double-click on a word, a window opens which lists the different ways a word is used. You can then choose the item which describes the way in which the word is used in the sentence you are reading, or you can click on other items to understand more about the other ways in which the word can be used.
You can find out more about the Double-Click Dictionary Plugin and get the code for it here.
