One word was close to breaking the internet on Wednesday morning: “covfefe”.
It was an apparent typo in a tweet by US President Donald Trump, and internet users have been mocking him mercilessly.
“Despite the constant negative press covfefe,” he tweeted just after midnight, Washington time.
And he then appeared to have gone to bed, without finishing his thought or correcting his mistake.
It took six hours before he acknowledged it with a good-humoured response, and by that time a lot of people had had a lot of fun.
White House Press Secretary Sean Spicer was asked by journalists at Wednesday’s daily briefing what the tweet meant.
Mr Spicer provoked incredulity from the assembled media as he replied: “The president and a small group of people know exactly what he meant.”

Although it seems likely the word Mr Trump was reaching for was “coverage”, social media users have been trying to guess other alternatives or motivations.
Others deliberated on the pronunciation, and wondered why no aides had stepped in to alert him to the mistake.
Google Translate recognised the word as Samoan, though could offer no English translation. A BBC reader has written in to debunk any suggestion that the president is a secret Samoan speaker. Among many other reasons for this, the language does not even have a letter C.
