Word family

The -ay word family

The answer

The -ay word family is every one-syllable word that ends in the rime ay, said /ay/. Our lexicon has 23 public words in it: 11 with one consonant first and 12 with a blend.

What is in this family?

The ay family is the long a sound at the very end of a word. It is the clearest example of the ai or ay position rule: every word here ends in ay because English words rarely end in i. All the words are one syllable, and most are very common (day, way, say, play), so students meet this family early in books. Gray is the American spelling; grey is British.

Word ladder: change one sound at a time

Every step is a real word from the list, and each one changes exactly one sound. Say the change aloud before the student writes the new word.

Rhymes spelled another way

These words rhyme with the family but spell the rime differently, so they belong to other families. Expect students to mix them up when spelling.

How do you teach it?

Teach ay alongside ai, after silent e. Start with one-sound onsets (day, say, pay, way), then blends (play, stray, spray, sway). Students say "end of the word, so ay" each time they write one.

"Where is the long a in 'stray'? At the very end. Nothing comes after it. So we write a-y. Now take away /t/ and /r/ and put /p/ and /l/ in front: play. Same ending, same spelling."

What is the common error, and the fix?

Students write "dai" or "plai". The fix is the position rule: long a at the very end of a word is spelled ay.

Sort it: a hands-on activity

Mix ay cards with ai cards (mail, rain, paint). Students sort by where the long a sits: at the end or in the middle. The ay pile should hold only end-of-word sounds.

How this list was built

Every word comes from our lexicon of about 19,000 common words, each checked against a pronouncing dictionary and split into spelling units. Words a student meets in our assessments and progress-monitoring probes are left out, so practicing a list never rehearses a test. A family is every one-syllable base word (no suffix, not a compound) whose rime, the vowel unit and every unit after it, has the same spelling and the same sounds, so bead and bread are in different families. Ladders use only words from the list, and each step changes exactly one sound.

"Readable after" is the first lesson in the lesson sequence at which our decodability engine finds every sound-spelling in the word taught; "not taught" means the word has a spelling the sequence does not cover, so it is read with help. You can check your own lists and passages with the free decodable text checker.

Questions people ask

How many words are in the -ay family?

Our lexicon has 23 one-syllable words ending in ay that a student can practice. Words used in our assessments are left out, so a few common words may be missing from the list.

Why do these words end in ay and not ai?

English words almost never end in the letter i, so a long a that closes a word is spelled ay. Inside a word, before a consonant, it is ai.

What is a word ladder?

A chain of real words where each step changes one sound: swap a sound, add one, or take one away. Students say the change before they write it, which trains them to hear every sound in the word.
