You may have encountered the phrase "I before E except after C" during your school years, and you’re likely aware that it has plenty of exceptions. So many, in fact, that it can be tough to keep track of them all! That’s why we’re here. In this article, we’ll break down the "i before e except after c" rule, explore its numerous exceptions, and discuss its origins—plus why English spelling can be such a challenge in the first place.
Understanding the "I Before E Except After C" Rule
The phrase "I before E except after C" is a helpful mnemonic designed to remind English speakers of the spelling pattern for words with "ie" or "ei." It works for words like "believe" or "ceiling," but there are many exceptions, which makes the rule less universally applicable.
Steps
What does the phrase “I before E except after C” mean?

- Example: In “friend,” the “i” precedes the “e” because there is no “c” before them.
- Example: In “ceiling,” the “e” comes before the “i” because the letters follow a “c.”
Is the “I before E except after C” rule accurate?

- Some suggest shortening the rule to simply “I usually comes before E,” as the “except after C” portion is inaccurate more often than not.

- I before E, except after C
Or when sounded as A as in 'neighbor' and 'weigh'
Unless the C is part of a 'sh' sound as in 'glacier'
Or it appears in comparatives and superlatives like 'fancier'
And also except when the vowels are sounded as E as in 'seize'
Or I as in 'height'
Or also in '-ing' inflections ending in '-e' as in 'cueing'
Or in compound words as in 'albeit'
Or occasionally in technical words with strong etymological links to their parent languages as in 'cuneiform'
Or in other numerous and random exceptions such as 'science', 'forfeit', and 'weird'. - The full version of the rhyme is so over-the-top that it’s inspired a popular “I before E except after C” meme template, where users humorously create their own explanations using words that defy the rule (for example, “...except when your foreign neighbors Keith and Heidi seize their eight sleights from feisty weightlifters”).

Where did the saying “I before E except after C” originate?

- Extensions such as the 1880 modification, “...or when sounded as ‘A’ as in ‘neighbor’ and ‘weigh’,” aimed to improve the rule’s accuracy, but English's complex linguistic influences are too varied to capture in one catchy rhyme.
What makes English spelling so tricky?

- The final major external influence occurred when the Norman French conquered England in 1066, replacing much of the existing vocabulary with French terms (words like “etiquette” or “ballet” have French origins).
- Later, during the “Age of Exploration,” the British Empire’s expansion introduced words from Africa, India, the Americas, and beyond into English.
- This blending of linguistic influences is the reason why English spelling rules are often inconsistent and why words that look alike may be pronounced differently (such as “though” and “through”).
