Why are words like privacy pronounced like /ˈprɪv.ə.si/ in British and /ˈpraɪ.və.si/ in American English (short vowel in the first case, long in the latter one)?
I read that determining whether a vowel is short or long, one must split the word in syllables, and then if that vowel is the only one in the syllable and is not succeded by a consonant is long, but if that vowel is still the only one in the syllable but is followed by a consonant in the same syllable is short. In the case of privacy I think it is because of the different spellings (priv-a-cy in British and pri-va-cy in American). If so, do you know other words that have different spellings in British than in American?
