The -old, -ild, -ind and -ost families

Closed syllables with a long vowel. Cold, child, find and most all break the short-vowel rule, and they are common enough to be taught as a set.

Child explanation

Cold, child, find and most look like they should have a short vowel, but they do not. These little groups keep the long sound.

The rule

In the -old, -olt, -ild, -ind and -ost families the vowel is long even though a consonant closes the syllable. These are closed sets and are learned as families.

What is really going on

Middle English lengthened vowels before certain consonant clusters — ld, nd, mb, mb and st among them — and the lengthening survived in these sets while the general rule did not. The sets are small and closed, which is precisely what makes them teachable as families rather than as exceptions.

Why English does this

The vowel lengthened before the cluster around eight hundred years ago. It is the same process that gives climb, comb and behind their long vowels.

Position in the word

• End of a word — The rime of a one-syllable word, or the stressed syllable of a longer one. For example: cold, child, find, most.

When this rule does not work

• The word is wind (the moving air), which is short, unlike wind (to turn).
• The word is lost, cost or frost, which are short despite ending -ost.

Examples

Easy examples

cold, old, child, find, most

More examples

gold, hold, told, bold, fold, sold, wild, mild, kind, mind, blind, behind, post, host, colt, bolt

Pseudo-words

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

frold, shind, blost

Exceptions

• -ost that stays short: lost, cost, frost. The lengthening did not apply to these.
• wind: wind. Two words, one spelling: /wɪnd/ the air, /waɪnd/ the action.

Contrast pairs

• cot versus cold — Short o versus the -old family.
• fin versus find — Short i versus the -ind family.
• most versus lost — Both end -ost; only one is long.

Decodable sentences

• The child will find the gold in the cold.
• Most of us hold on and do not mind.
• Be kind to the wild old bird.

Do not teach it like this

"A vowel before two consonants is always short."

Cold, child, find, most, old and kind are all frequent, all early, and all long.

"Usually short — but there are a few families that stay long, and here they are." Then teach them as a chant.

Teacher note

Teach these as rhyming families with a chant, not as exceptions. They arrive at roughly the same time as open and closed syllables, and naming them then prevents months of hesitation on some of the most frequent words in early reading.

Learn these first

• The five short vowels — a e i o u in a closed syllable — A single vowel with a consonant after it and nothing else is usually short. This is the rule that makes CVC words decodable.
• Closed syllable — CVC — A syllable ending in a consonant. The vowel is short — the most reliable vowel generalisation in English.

• The -all, -alk and -alt families — -all -alk -alt -alm — After a, the letter l changes the vowel to /ɔː/ — and in -alk and -alm the l goes silent as well.
• Silent L in selected word families — alk / alm / alf / olk — L is silent in a small set of established families — walk, calm, half, folk — and in almost nothing else. Milk, silk, help and salt all keep their l.

• Previous in Glued and welded sounds: Glued sounds: ank, ink, onk, unk — ank / ink / onk / unk — The n in these is /ŋ/, not /n/. Four rimes, taught whole for the same reason as ang and ing.
