USAGE NOTE:
Many words, such as honor, vapor, and labor, are usually spelled with an or ending in American English but with an our ending in British English. The preferred spelling of glamour, however, is our, making it an exception to the usual American practice. The adjective is more often spelled glamorous in both American and British usage.
