<P> In a few cases, essentially the same word has a different spelling that reflects a different pronunciation . </P> <P> As well as the miscellaneous cases listed in the following table, the past tenses of some irregular verbs differ in both spelling and pronunciation, as with smelt (UK) versus smelled (US) (see American and British English differences: Verb morphology). </P> <Table> <Tr> <Th> UK </Th> <Th> US </Th> <Th> Notes </Th> </Tr> <Tr> <Td> aeroplane </Td> <Td> airplane </Td> <Td> Aeroplane, originally a French loanword with a different meaning, is the older spelling .

According to the OED, "(a) irplane became the standard American term (replacing aeroplane) after this was adopted by the National Advisory Committee for Aeronautics in 1916 . Although A. Lloyd James recommended its adoption by the BBC in 1928, it has until recently been no more than an occasional form in British English ." In the British National Corpus, aeroplane outnumbers airplane by more than 7: 1 in the UK . The case is similar for the British aerodrome and American airdrome; Aerodrome is used merely as a technical term in Australia, Canada and New Zealand . The prefixes aero - and air - both mean air, with the first coming from the Ancient Greek word ἀήρ (āēr). Thus, the prefix appears in aeronautics, aerostatics, aerodynamics, aeronautical engineering and so on, while the second occurs invariably in aircraft, airport, airliner, airmail etc . In Canada, airplane is more common than aeroplane, although aeroplane is used as part of the regulatory term "ultra-light aeroplane". </Td> </Tr> <Tr> <Td> aluminium </Td> <Td> aluminum </Td> <Td> The spelling aluminium is the international standard in the sciences according to the IUPAC recommendations .
