Earlier this year, it was revealed that we probably have to take President Donald Trump’s tweets seriously – and that anything the political boggart says on Twitter could potentially be used as evidence against him in court.

You’d be forgiven for thinking, then, that this might inspire the POTUS to start checking his social media posts for spelling mistakes before posting them online. However, this is Trump we’re talking about – and so, in a furious tweet about the “mainstream media’s” obsession with his misspelling, he ended up dropping in a typo. Oops.

“After having written many best selling books, and somewhat priding myself on my ability to write, it should be noted that the Fake News constantly likes to pour over my tweets looking for a mistake,” he wrote.

“I capitalize certain words only for emphasis, not [because] they should be capitalized!”

Of course, you don’t need us to tell you that Trump intended to say that the media likes to “pore over” his tweets, rather than “pour over.” Pore over, as you already may know, means to minutely study the contents of an object, which would also include a piece of writing.

The latter, on the other hand, means to cause a liquid to flow from a container in a steady stream (such as milk from a bottle).

Of course, it didn’t take long for Trump’s mistake to be noticed – and by none other than professional writer, typo-chaser and Trump botherer, JK Rowling.
