The differences between British English and American English
There are three noticeable diffreences between British and American English. First, there are some differences in pronunciation; for example, speakers of British do not always pronounce ‘r’. In British English, the word ‘schedule’ is pronounced [shed-u-al]; in American English it is pronounced [sked-u-al].
A second difference is the spelling of the words; for instance, the British use ‘colour’, the Americans use ‘color’. The British spell ‘realise’ with ‘s‘, but the Americans spell it ‘realize’ with ‘z‘. In American English, the word ‘defence’ is spelt ‘defense’ with ‘s‘.
Finally, there is some vocabulary in British and American English that expresses the same meaning, but they have different forms such as ‘petrol‘ for ‘gas‘, ‘pocket money’ for ‘allowance‘, and ‘bonnet‘ for ‘hood‘.
