You might have already known that you can look-up word definitions directly from within Chrome. For example, you can type a phrase in the Omnibox and it almost instantly retrieves the definition.
Alternately, you can just type the same phrase from Google’s homepage and get the same result; however, today you’ll see more than just a solitary definition.
Google Search now includes synonyms and complete sentences that exemplify proper usage; in other words, you get to see the word in context.
The new feature is limited to the US right now but Google may expand to other locals as the new tool becomes ascendant.
