Utilization is the correct spelling of the noun derived from the verb to utilize.
In British as well as American English. There is no 'utilise' in the Oxford English Dictionary, although it notes -ise as an alternative ending. This was a plot feature in one of the Inspector Morse stories, with Morse differentiating between an 'educated' and an 'uneducated' man by their correct use of -ize on a number of English words that are spelt that way. There is no universal "-ise is British English and -ize is American English' rule. Similarly several British English -ise words take a z in the noun form. Oddly enough, the alternate spelling 'utilise' is one of them. Time, perhaps, for the OED to be updated. 'Utilisation' appears in Google ten times as often as the (correct) 'utilization'. -- Phil Payne http://www.isham-research.co.uk +44 7833 654 800 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
