Wikipedia: I before E except after C
“I before E, except after C” is a mnemonic rule of thumb for English spelling. If one is unsure whether a word is spelled with the sequence ei or ie, the rhyme suggests that the correct order is ie unless the preceding letter is c, in which case it is ei.
(...)
Some authorities deprecate the rule as having too many exceptions to be worth learning.
