i Before e
You may know the rhyme: "i before e, except after c, or when sounding like a, as in neighbor and weigh." It's useful, but it has a lot of exceptions. Here's the reliable version: ie for the long e sound (piece, field), ei after c (receive) and ei for the long a sound (eight).
The rule, made reliable
The rhyme works best when the letters say long e, as in see. Then it's usually ie: piece, field, believe, chief, niece, thief. Right after a c, it flips to ei: receive, ceiling, receipt, deceive.
When the letters say long a, as in day, it's ei: eight, weigh, neighbor, vein, sleigh. Many other words, like their, weird, seize, either, science and friend, don't follow the rhyme at all, so they're learned as tricky words.
Long e sound: ie (piece), but ei after c (receive).
Long a sound: ei (eight, weigh).
In 4th and 5th grade, kids are expected to spell grade-level words correctly and check a dictionary when unsure (L.4.2d, L.5.2e). For other common spelling traps, see commonly misspelled words.
ie and ei words
Listen to the sound the two letters make.
| Pattern | Sound | Words |
|---|---|---|
| ie | long e | piece, field, believe, chief, niece, thief, shield, yield |
| ei after c | long e | receive, ceiling, receipt, deceive, conceit |
| ei | long a | eight, weigh, neighbor, vein, sleigh, freight, reign |
| ie | long i | pie, tie, lie, cried (y changed to i) |
| Exceptions (learn by heart) | various | their, weird, seize, either, neither, protein, science, friend, ancient |
Words where y changed to i, like cried and babies, aren't really part of this rule. See change y to i.
