It appears not to have taken Prince Harry long to drop the Queen's English after the Duke of Sussex let an Americanism slip during a recent web chat.
Harry and wife Meghan Markle appeared on the Time100 Talks web chat to talk about improving online communities on Monday, October 19.
The digital experience promised to "dive into the state" of the internet and aims to bring together "experts, advocates and online creators to elevate essential world conversations".
During the talk, Prince Harry used the American phrase "pop the hood" instead of the traditional Queen's English term "bonnet".
Introducing some of the social media experts on the chat, which included Reddit co-founder Alexis Ohanian and Tristan Harris of Netflix hit Social Dilemma, to speak the duke slipped into an Americanism.
He said: "When driving a car and all the warning lights are going off, there is smoke pouring out of the hood.
"You are not going to keep on driving.
"You pull over.
"In the olden days, you'd probably pop the hood up, have a look under it and maybe fix it.
"But now, every single one of these new cars has a shield over top so you can't fix it - you've got to call experts in."
He added: "The online world is affecting the world.
"It is not restricted to certain platforms of social media groups. This is a global crisis.
"A global crisis of hate. A global crisis of disinformation and a global health crisis.
"These people we speak to there is no one else better to explain it."
The couple announced in January this year that they would step back from senior positions in the Royal Family following talks at Sandringham between Harry, Prince Charles, Prince William and the Queen.
Meghan and Harry have since relocated with their son Archie Harrison to California, having spent the intervening period living in Canada, in hopes of a more private lifestyle.
During the talk, TIME editor-in-chief Edward Felsenthal had started the internet special by asking the Royal pair how they were doing being locked down in their new LA pad – something Harry was keen to point out was much more significant than it used to be.
He said" "I think when people ask, 'How are you?' I sense, you know, it's a case of 'Really, how are you?'
"Before this year, I think everyone sort of throws that term around and everyone's satisfied with a 'Yeah, I'm good. I'm fine, thanks.'
"And then it's moving on to something else."
"But I think you're quite right. This year, more so than ever, it really is a question of 'No, no, no. Actually, how are you?'
Meghan was quick to shine a light on the way the pandemic had allowed them both to spend more time with young son Archie.
"All things considered, everyone is grappling with a different version of the same thing," she interjected.
"For us, we're trying to embrace all of the quality time we get with our son right now and to not miss a single moment of his growth and development, which has been really special."
