Not to mention plenty of examples of words containing “cie”. e.g. ancient, efficient. A more complex version of the rule adds “except when the “c” is pronounced “sh” (and pronunciation of these words varies regionally), but that still doesn’t pick up words containing “cie” where the “i” has the long vowel sound (e.g. “society”, “science”), as well as all the plurals of words ending in “cy” (e.g. “policies” — and virtually all such words were originally spelled “cie” in the singular). And it’s also fairly common to see names ending in “cie” — some are of non-English origin, but as a diminutive ending for female names (often, but not always an alternate to “cy” spelling), it’s perfectly English, as is the name of the official NYC Mayor’s residence “Gracie Mansion”, which is named after a Scotsman surnamed Gracie. Think how idiotically wrong it would look if you saw “Gracei”, and no one would be sure how to pronounce it.
Christie as well.
