Long Vowels: igh, y, oa, ow and Silent e (light, fly, boat, snow)
Learn spellings for the long i and long o sounds: igh, y and i_e, oa, ow and o_e. Use the position rules, study the word bank and practise spelling.
The idea
The long i sound, as in light and fly, and the long o sound, as in boat and snow, can each be spelled several ways. Long i can be igh, y or i with a silent e: light, fly, bike. Long o can be oa, ow or o with a silent e: boat, snow, bone.
Position helps. In the middle of a word, long i is often igh (light, night, high), and long o is often oa (boat, coat, road). At the end of a word, long o is usually ow (snow, grow, slow), because English words almost never end in oa. A short word that ends in long i is usually spelled with y: my, fly, try.
The silent e pattern is a third choice. Compare bik and bike, or bon and bone. The silent e at the end of the word makes the vowel before it say its name. Words like time, kite and home follow this pattern.
These are strong patterns, but they have exceptions. Cow has ow but says the ou sound, and pie spells long i with ie. When you are unsure, say the word slowly, decide where the vowel sound is, try the likely spelling and check it against a word bank or a dictionary.

Worked examples
Example 1 · igh, y or i_e?
Choose the spelling: "The kite flew h___." (igh / y / ie)
- Say the word: high. The long i sound is at the end, but the word is not a short word like fly.
- High is one of the common igh words, along with light and night.
- Check the word bank: high.
high (igh)
Example 2 · oa or ow?
Choose the spelling: "The first sn___ fell in November." (oa / ow)
- Say the word: snow. The long o sound is at the end of the word.
- English words almost never end in oa, so the end spelling is ow.
- Check the word bank: snow.
snow (ow at the end)
Example 3 · Silent e
Which is correct for the thing you pedal: bik or bike?
- Say the word: BYKE. The i says its name, the long i sound.
- A silent e at the end of the word makes the i say its name.
- Without the e, bik would be said with a short i.
bike (i with a silent e)
Common mistakes
Why this fails: At the end of a word the long o sound is usually spelled ow: snow, grow, slow. Oa belongs in the middle: boat, coat, road.
Why this fails: Without the e, the vowel says its short sound. Bike and home need the silent e for the long vowel.
Why this fails: Nite and lite are shortcut spellings seen in advertising. Standard English uses igh: night, light.
Why this fails: Cow and now have ow but say the ou sound. Say the word aloud before choosing a spelling pattern.
Why this fails: Long i is spelled igh (light), y (fly), i with a silent e (bike) and, in a few words, ie (pie). Learn the common patterns and the exceptions.

Answer key
- 1. igh
Igh makes the long i sound in light, night and high. Ie appears in a few words such as pie, but it is not the pattern here. Ai and oa are vowel teams for other sounds. - 2. oa
Oa in the middle of a word makes the long o sound: boat, coat, road. Ow usually comes at the end, as in snow. Ou and oi make different sounds. - 3. fly
A one-syllable word that ends with the long i sound is often spelled with y: fly. Fli and flie are not English spellings, and figh is not a word. - 4. snow
The long o is at the end of the word, so it is spelled ow: snow. Snoa puts oa at the end, which English words almost never do. Sno and snoe are not the correct spellings. - 5. It makes the i say its long sound
The silent e at the end makes the vowel before it say its name: bik with no e would not say BYKE. The e is silent, it does not change k, and it has nothing to do with plurals. - 6. bone
Bone uses o and a silent e to make the long o sound. Boan and bown are not English spellings, and bon would be said with a short o. - 7. try
Try is a short word that ends in the long i sound, so it ends in y. Trie and tri are not English spellings. Trigh uses igh, which belongs in the middle or at the end of words like high, not here. - 8. coat
Coat is the spelling with oa. Cote is a real word for an animal shelter, but it does not mean a piece of clothing. Cowt and koat are not English spellings. - 9. night
Night is spelled with igh. Nite is a shortcut spelling used in advertising, not standard English. Nyte and nigt are not correct spellings. - 10. grow
Grow ends with ow. Road and boat use oa in the middle, and bone uses o with a silent e. - 11. The boat was slo.
Slo should be slow, with ow at the end for the long o sound. The other three sentences are spelled correctly. - 12. light, kite, fly
Light, kite and fly all say long i. The first wrong list holds only long o words, the second holds only long o words too, and the last mixes in boat, a long o word. - 13. cow
Cow has ow, but it says the ou sound, as in out. The ow spelling is not always long o, so say the word aloud. Home, slow and coat all say long o. - 14. pie
Pie spells long i with ie. Light uses igh, bike uses i with a silent e, and my ends with y. A few words use ie, but igh, y and i_e are more common. - 15. They all follow the rules: kite, boat, home
Kite uses i with a silent e, boat uses oa in the middle, and home uses o with a silent e. Kyte, bote and hohm copy the sounds without using the standard spelling patterns, and hom and kiet are also not correct spellings.
