This document discusses spelling conventions in British and American English. It begins by defining spelling as the representation of sounds in a written language using graphemes. It then provides examples of differences in spelling between British and American English, such as words ending in "-our" versus "-or", verbs ending in "-ise" versus "-ize", and the doubling of consonants in certain verb endings in British English. It also notes that British English retains spellings from other languages like French and German more often than American English. The document concludes by stating that both spelling conventions are generally acceptable unless writing for a specific audience.
