In Microsoft Edge on the context menu there is an option to 'Define' a highlighted word or phrase. Example below is to 'Define Tectonics' -- note the word 'tectonics' highlighted below the context menu.
Click the 'Define tectonic' button and up pops a window defining the word. Note there is a button to 'speak' the word. Note also there is a further option to 'Search for Tectonics.'
Click the 'Search for tectonics' and a sidebar opens up, as shown below, that allows more words to be defined, the word or phrase to be translated into other languages, and presents further defined phrases for the word to be explored.
