Online Dictionary by Google
Google the company that for many has come to define the Internet, has quietly rolled out an online dictionary offering the meanings of words in more than two dozen languages.
A visit to a Google Dictionary service at google.com/dictionary shows a clean, simple webpage with a box for selecting languages from a drop-down list and a second box for typing in words to be defined.
I search the video demo from You Tube but I cannot find one. Anyway Google Dictionary is simple, and you can use it with ease. The dictionary service offered definitions of words in 28 languages and to translate terms for or into English. Cool and it is really helpful.
