I before E except after C

I before E except after C is a spelling rule used in English. This rule of thumb is not always true. However, if we interpret it correctly it can be useful.

If the pronunciation of a vowel is stressed /iː/ and you are not sure if you should spell "ie" or "ei" then go for "ie" except in /siː/ which is "cei".

A shorter form is

I before E except after C if the vowel-sound rhymes with bee.

Examples

You are not sure if it's "chief" or "cheif". The rule helps you to spell "chief".

You are not sure if /siːlɪŋ/ is "seiling", "sieling", "ceiling", or "cieling". The rule tells you it's "ceiling".

You are not sure if /ˈsiːʒər/ is "seizure", "siezure", "ceizure" or "ciezure". The rule misleads you into thinking it's *"ceizure", or maybe *"siezure".

You don't know how to spell /ˈfriːkwənt/. The rule tells you it is not "freiquent" and it might be "friequent". However, the actual spelling is "frequent".
