Some large groups of words have "cie" in the spelling. Few common words have the "cei" spelling handled by the rule: verbs ending "-ceive" and their derivatives ("perceive", "deceit", "transceiver", "receipts", etc.), and "ceiling". The BBC trivia show "QI" claimed there were 923 words spelled "cie", 21 times the number of words that conform to the rule's stated exception by being written with "cei". These figures were generated by a QI fan from a Scrabble wordlist. The statistic was repeated by UberFacts.
