possibility "The Cowboys won the game Saturday" would have the equivalent in the UK of "Sheffield United won the match on Saturday." Figures of speech Both BrE and AmE use the expression "I couldn't care less", to mean that the speaker does not care at all. Some Americans use "I could care less" to mean the same thing. This variant is frequently derided as sloppy, as the literal meaning of the words is that the speaker does care to some extent. In both areas, saying, "I don't mind" often means, "I'm not annoyed" (for example, by someone's smoking), while "I don't care" often means, "The matter is trivial or boring". However, in answering a question such as "Tea or coffee?", if either alternative is equally acceptable an American may answer, "I don't care", while a British person may answer, "I don't mind".

It can also have an additional meaning in AmE of "to be finished or done", for example, a customer at a restaurant telling a waiter "I'm all set. I'll take the check." Equivalent idioms A number of English idioms that have essentially the same meaning show lexical differences between the British and the American version; for instance: In the US, a "carpet" typically refers to a fitted carpet, rather than a rug. Social and cultural differences Lexical items that reflect separate social and cultural development. Education Primary and secondary school The US has a more uniform nationwide system of terms than does the UK, where terminology and structure varies among constituent countries, but the division by grades varies somewhat among the states and even among local school districts. For example, elementary school often includes kindergarten and may include sixth grade, with middle school including only two grades or extending to ninth grade. In the UK, the US equivalent of a high school is often referred to as a "secondary school" regardless of whether it is state funded or private. US Secondary education also includes middle school or junior high school, a two- or three-year transitional school between elementary school and high school. "Middle school" is sometimes used in the UK as a synonym for the younger junior school, covering
