"i before e" exceptions to the rule. (please read the entire rule on my tips page, then if you find another true exception email me!)
e before i words
either (depending on how you pronounce it, it is or isn’t an exception)
neither (depending on how you pronounce it)
i before e after c
(Remember: There are no "cein" words in the English language! If you have a c followed by an ie/ei combination, and followed by an n, It is ALWAYS an ie as in science, ancient, etc.
