Overseen in D’s new book, Rocky Dog. Is it me or does this just look weird?
Okay, here’s the deal: you can spell it glamor, this is totally a-okay. But unlike words such as honor or labor, which are commonly spelled -our in British English and -or in American English, glamor just doesn’t seem right.
American Heritage explains:
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.
The Columbia Guide to Standard English chimes in, “Both glamour and glamor are Standard spellings, although glamour is more frequent.”
