Amazon’s new show, The Grand Tour has landed—no stormed—into our lives. The first episode, which aired Nov. 17, was Amazon’s most watched premiere.

But some of the show’s millions of viewers out there might have been confused at times, even as they laughed at the one-liners and sat in suspense as the track battle between the Porsche 918, McLaren P1, and Ferrari LaFerrari played out.

The Grand Tour is a big budget reprisal of the BBC’s Top Gear with its longtime co-presenters Jeremy Clarkson, Richard Hammond and James May.

Clarkson, Hammond, and May are all, of course, from the UK. Which means they speak English. Not “American.” And that can be confusing to our unsophisticated ears. The presenters even touched on this, ever so briefly in the first episode.

We’ve put together a guide of sorts that provides a translation on car parts and terms, as well as a few other sayings that pop up in the episodes. Fortune will update it on occasion as necessary. You never know when a new car term or turn-of-phrase will end up in The Grand Tour. There are 11 episodes left. We’re here all season.

The guide:

A bonnet is a hood, not the headgear worn by babies and 17th century ladies.

A boot is a trunk, not what cowboys wear. It’s also not a device slapped onto a vehicle’s tire by city law enforcement for failure to pay fines, that’s a clamp.

A cubby box is a glovebox, not the space where kindergarteners place their backpacks and lunches.

A dynamo is a generator, not an energetic person or professional sports star.

A hood is a convertible top, not the hood of a car. That’s a bonnet.

Lorry is a semi truck, not a woman’s name.

Petrol is fuel, not a—wait you should really know what petrol is even if you’ve never been out of the United States. Read a book.

Saloon is a two- or four-door sedan, not a bar where boot-wearing cowboys and gamblers hang out. This is not Tombstone in the 1880s.

Side curtains are removable windows, not a piece of cloth used to shield light and all those prying eyes trying to see inside your VW microbus. We all know what you’re smoking.

A silencer is a muffler, not the firearm accessory used in movies.

A torch is a flashlight, not a piece of wood wrapped in cloth that’s been soaked in tallow and lit on fire to provide light. Nobody does that anymore, except maybe on Survivor.

A wing is a fender, not the spicy sauce-laden bar food made of chicken, but called buffalo.

Episode 2 of The Grand Tour is available on Amazon Video on November 25.
