The Longman Dictionary for the English language is world renown for its easy to understand definitions and perhaps this is why many of the English teachers recommend this for the students who are learning English as their second language. Longman English Dictionary offers a web based search at ldoceonline.com where you can lookup for the definition of any word or phrase. They also have an app for Android and iOS devices. But if you want much quicker and pain-free results from Longman English Dictionary, then you can use the free Longman English Dictionary Browser.
Longman English Dictionary Browser is a small program that stays docked in the Windows desktop system tray. And whenever you need to lookup for the definition of any word or phrase, you can select that word n any text editor (like Notepad) or web browser and use the hotkey Ctrl+Shift+D. If you want to hear how a word sounds, then you can use the hotkey Ctrl+Shift+S and it will invoke the online text-to-speech engine.
A small browser window will open showing you the definition of that word. What this application seems to do is load the small web browser to the web page address of the http://www.ldoceonline.com/dictionary/ showing the definition of the selected word. For example, if you look for the word “conducive”, then it will load the web page at http://www.ldoceonline.com/dictionary/conducive.
In the right-click system tray menu, you can change the hotkeys assigned for looking up the definitions, for invoking text-to-speech engine, and choose to toggle auto-start with Windows, and more. From here you can also pick whether you want to use US English or UK English for the text-to-speech engine.
Conclusion: The Longman English Dictionary Browser makes it very convenient for you to lookup the words and phrases using the online Longman Dictionary web site. However it needs an active internet connection for working. Had it been an offline application, it would have topped the charts in all the dictionaries available for Windows PC.
