The OULD family

Would, could, should — three words, a silent l, and a pattern that does not generalise. Shoulder and boulder keep their l.

• /ʊd/ ould: would, could, should

Where Wiggler teaches it: Skill 5: Glued Sounds & Spelling Basics · Skill 11: Advanced Patterns & Silent Letters

Child explanation

Would, could and should all rhyme. The l is quiet in all three. There are only three words like this.

The rule

Would, could and should are pronounced /wʊd/, /kʊd/ and /ʃʊd/. The l is silent and the ou is /ʊ/. This is a three-word family, not a rule about oul.

What is really going on

A closed set of three modal verbs. The l in could is not even historical — it was inserted by analogy with would and should, where it was. The pattern does not extend: shoulder, boulder, mould and soul all pronounce the l.

Why English does this

Would and should come from verbs that really had an l. Could did not — its l was added in the sixteenth century because scribes thought it should match.

Position in the word

• End of a word — The whole word. For example: would, could, should.

When this rule does not work

• The word is shoulder, boulder, mould, soul or poultry, all of which pronounce the l.

Examples

Easy examples

would, could, should

More examples

wouldn't, couldn't, shouldn't

Exceptions

• oul with a pronounced l: shoulder, boulder, mould, soul, poultry. The silent l belongs to these three words, not to the letter sequence.

Contrast pairs

• could versus shoulder — The same four letters, and the l is silent in one and said in the other.
• would versus wood — Homophones with different spellings.

Do not teach it like this

"L is silent in the oul pattern."

Shoulder, boulder and soul all say it. The silence belongs to three specific words.

"Would, could and should are three words that rhyme and have a quiet l. Learn them together."

Teacher note

Teach all three in one go, as a rhyming trio, early — they are among the most frequent words in English and children meet them long before silent l is taught. Keep them entirely separate from the -alk family, because joining them implies a generalisation that does not exist.

Related rules

• 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.
• Heart words — the · was · said · come · some — Words with one part that cannot be decoded. Sound out the part that works, and learn by heart only the part that does not.
• OU — ou — /aʊ/ in cloud is the main value, but ou also gives /ʌ/, /uː/, /ʊ/ and /ɔː/. One of the most variable teams in English.
• OO and its two sounds — oo — /uː/ in moon and /ʊ/ in book. Roughly three to one in favour of moon, with no spelling clue — but a strong clue in the following consonant.

• Previous in Irregular and heart words: Heart words — the · was · said · come · some — Words with one part that cannot be decoded. Sound out the part that works, and learn by heart only the part that does not.
• Next in Irregular and heart words: The AUGH family — -augh — Usually /ɔː/ with a silent gh — caught, taught, daughter. Laugh is the one that says /ɑːf/.
