The rhyme works for one small group of words, and then it falls over.
The rhyme
I before E,
except after C.
It is meant to help you spell words with the sounds ie and ei in them. It does help with believe, friend and piece, where i comes first. It also helps with receive, ceiling and deceive, where e comes first, because of the c before it.
Many people also learn a longer version, which adds a second clue:
I before E,
except after C,
or when sounded as A,
as in neighbour and weigh.
That extra line covers eight, neighbour, weigh and sleigh, where ei says A.
The weird part
Look at the word weird. It has e before i, and there is no c in sight. The word that describes the rule's problem is itself one of the rule's exceptions.
The short rhyme has many exceptions:
- eight, neighbour, weigh and sleigh: ei is correct without a c. The longer rhyme covers them, because ei says A.
- height and seize: ei again, with different sounds.
- science: here the c is followed by ie, which is the reverse of what the rhyme says.
- glacier: the c sounds like sh, and the ie is back where the rhyme does not expect it.
Why does it happen?
Merriam-Webster explains that the rhyme was made after most of the words were already in English. It reliably covers a small group, mostly words that came from French, such as receive, deceive and receipt.
Many exceptions come from other sources. Eight, weigh, neighbour, sleigh and weird come from Old English roots. English kept collecting words from different places, and the spelling never settled into one tidy rule.
Common mistakes
The rhyme does not cover every word.
❌ wierd
✅ weird
After C, it is EI.
❌ recieve, cieling
✅ receive, ceiling
The A sound uses EI.
❌ nieghbour
✅ neighbour
In a conversation
Mia: I before E, except after C.
Sam: So how do you spell weird?
Mia: W-E-I-R-D.
Sam: But that is E before I, and there is no C.
Mia: Exactly. That is why it is weird.
The OddLingo takeaway
Use the rhyme as a hint for words that sound like ee, such as receive and believe. If the word is not on its small list, check it. And if the word does not behave, blame its history.
For a word where the rhyme works but another letter misbehaves, see Receipt: it has the ei after c that the rhyme expects, plus a silent p. For a word that breaks the rhyme, see Neighbour.
