Open syllable

A syllable ending in a vowel. The vowel is long — go, me, hi, robot, paper.

• /eɪ/ /iː/ /aɪ/ /əʊ/ /juː/ long vowels: go, me, hi

Where Wiggler teaches it: Skill 7: Open & Closed Syllables + Y · Skill 12: Multisyllable Decoding

Child explanation

When nothing shuts the vowel in, it says its name. Go, me, hi, she.

The rule

An open syllable ends in a vowel, and that vowel is usually long. This is what makes go, me and she work, and what makes the first syllable of robot and paper long.

What is really going on

Reliable in stressed position. In unstressed position an open syllable reduces to schwa — the first syllable of about and the second of animal — so the rule is really about stressed open syllables. The commonest breaks are the very frequent function words to, do and who.

Position in the word

• One-syllable words — The whole word is one open syllable. For example: go, no, me, he, she, hi.
• Stressed syllable — The first syllable of a two-syllable word. For example: robot, paper, tiger, open, music.
• Unstressed syllable — Reduces to schwa. For example: about, again, animal.

Examples

Easy examples

go, no, me, she, hi

More examples

be, we, so, my, why, robot, paper, tiger, open, music, table, baby, lazy

Pseudo-words

Made-up words that follow the rule. A child who reads these has the pattern rather than the vocabulary.

fo, prel, vibot

Exceptions

• to, do, who: to, do, who, into. Three high-frequency function words with /uː/ rather than long o.
• Unstressed open syllables: about, again, animal, banana. Reduce to schwa regardless of the vowel letter.

Contrast pairs

• go versus got — Open versus closed.
• me versus met
• hi versus hit
• ro-bot versus rob-in — Where the split falls decides the vowel.

Teacher note

Teach with closed syllables as a direct contrast, and use the split-the-word activity: ro-bot versus rob-in. The sorting is what teaches it — children who decide where to put the boundary and then read the result understand why the boundary matters, which no amount of explanation achieves.

Learn these first

• Closed syllable — CVC — A syllable ending in a consonant. The vowel is short — the most reliable vowel generalisation in English.
• The five long vowels and how they are spelled — a e i o u saying their names — A long vowel says the letter's name. Each one has four to eight regular spellings, and which spelling a word takes is largely decided by position.

Related rules

• Closed syllable — CVC — A syllable ending in a consonant. The vowel is short — the most reliable vowel generalisation in English.
• Syllable division — VC/CV · V/CV · VC/V — Where you split a word decides whether its vowel is long or short. Three patterns cover most of English.
• The letter Y — y — The clearest case in English of position deciding sound. Y is a consonant at the start of a word and a vowel everywhere else — and which vowel depends on how many syllables the word has.
• Schwa — any vowel letter, unstressed — The most common vowel sound in English, spelled with any vowel letter at all. It is why decoding every vowel fully produces a word nobody says.

• Previous in Syllable rules: Closed syllable — CVC — A syllable ending in a consonant. The vowel is short — the most reliable vowel generalisation in English.
• Next in Syllable rules: VCe syllable — v_e — The magic e syllable. Vowel, one consonant, silent e — and the vowel is long.
