Microsoft's personal digital assistant, Cortana, is gaining new features at a rapid pace. With Microsoft committing to updating the feature at least twice a month, it's a service that is constantly evolving.

In this edition of 'What can Cortana do now?", it looks like defining words has been recently added to service. Admittedly, we don't really know when this was added but a quick Google Bing search didn't show anything on the topic, so here you go. To have Cortana define a word, simply say "Define (insert word)" and she will go out and fetch the relevant information.

As noted by out tipster, this feature is quite handy for those trying to learn the English language. Because the results come back quickly, it's far faster than using Bing or Google to find the definition.

It is worth pointing out that this feature may not be available in all areas as our UK editor tried it on his phone but Cortana would not return a word definition when prompted.

It goes without saying that Microsoft is deeply committed to Windows Phone and is wanting Cortana to become a cornerstone of the mobile platform and likely the entire Microsoft ecosystem in the near future. By pushing out updates at a regular and frequent cadence, it won't take much time at all for the platform to quickly mature and become the top player in the virtual assistance fight against Google Now and Siri.

Thanks for the tip Leoberto!
