According to The Doctor, books are the best weapons in the world.

So Whovians should take great pleasure in knowing that the Oxford English Dictionary is adding one of the most important wibbly wobbly, timey wimey terms from Doctor Who as an official word.

Yes, it's true—come June 2017, the dictionary will define the famous extension of The Doctor himself, his go-to tool: the sonic screwdriver.

Oxford Dictionaries announced the exciting news in a brilliant blog post, reminding us all that much like the Tardis, an Oxford English Dictionary is magical, blue, and far more expansive than it appears from the outside.

As you can see from the preview image below, the versatile tool is defined as "a (hand-held) electronic device which uses sound waves to perform various mechanical and technical functions. Originally and chiefly in (or in reference to) the British television series Doctor Who."

It should also be noted the tool was recently referenced in WikiLeaks dump, which proves it truly is all the rage right now.

The screwdriver will be joining several of the dictionary's existing Doctor Who entries, like TARDIS, Dalek, and Cyberman. We've got a feeling it won't be the last.

After all, in over 900 years of time and space, The Doctor has never come across a word that wasn't important. 😉
