More accurately, what words and phrases differ for the same thing.
Various parts of a car are a good example: for example Americans find the engine under the "hood" rather than bonnet, load their luggage into the "trunk" (boot) and scrape the dead insects off the "windshield" (windscreen). Though for anyone owning modern cars, actually "finding" the engine under all the auxiliaries is a challenge irrespective of country and language....

Just spotted another, elsewhere on SW; but it may not be universal, possibly invented by some journalist:
"Heat Index", followed by a number of degrees "Fahrenheit".
"Temperature" is not a synonym for heat; and the rest of the world uses degrees-Celsius!
