Correct please.. Hello! Yes, you're right.At school we learn British English.That's why sometimes I don't understand what are you writing about. We learn Endlish three hours a week.In English class we study grammar rules,new words,regular and irregular verbs.I think it is very important. The difference between British English and American English is that words can written the same way, but pronounced differently.Also I heard Americans often substitude letters 't' and 'd' for a sound 'r' in a colloqual speech,is it true? I know some common vocabulary differences: lift (GB)-elevator(US) ; hiliday(GB)- vacation (US); pavement(GB) -sidewalk(US). I have 2 question for you! The first is: in British language when a word ends in a single consonant,it is doubled when we add vowel; for example: traveller ,but I heard it is another rule in American English.So,it will be correct to write traveler? The second question is: What does word "ain't" means?
