The -ed ending

/t/ in jumped, /d/ in played, /ɪd/ in wanted. Only the third adds a syllable, and only after t or d.

Strong rule · High reliability · Very common · Early · Reading and spelling

• /t/ after an unvoiced sound: jumped, kissed, walked
• /d/ after a voiced sound: played, hugged, cried
• /ɪd/ after t or d: wanted, landed, painted

Where Wiggler teaches it: Skill 13: Suffixes

Child explanation

Jumped ends with /t/, played ends with /d/, and wanted ends with /ɪd/ and has an extra beat. All three are spelled -ed.

The rule

The past-tense ending is /ɪd/ after t or d — and only then does it add a syllable. Otherwise it is /t/ after an unvoiced sound and /d/ after a voiced one.

What is really going on

The same voicing assimilation as -s, with an epenthetic vowel where the root already ends in an alveolar stop. The single most useful fact for a reader is the syllable test: -ed adds a syllable only after t or d, so jumped is one syllable and wanted is two.

Position in the word

• End of a word — The suffix position. For example: jumped, played, wanted.

When this rule works

• /ɪd/ only after /t/ or /d/.
• /t/ after /p/, /k/, /f/, /s/, /ʃ/, /tʃ/.
• /d/ after every other consonant and after any vowel.

Pseudo-words

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

blimped, shugged, franted

Contrast pairs

• jumped versus wanted — One syllable versus two — and the t before the ending is why.
• played versus kissed — /d/ versus /t/, both spelled -ed.

Decodable sentences

• We jumped and played until we wanted to stop.
• She washed the cup and filled it.
• They painted the shed and needed a rest.

Common reading mistakes

• jumped: a child reads /dʒʌmpɪd/ with two syllables, where the word is /dʒʌmpt/. The extra syllable added where there is none.
• walked: a child reads /wɔːkd/, where the word is /wɔːkt/. The wrong voicing, usually harmless in context.

Teacher note

Teach the syllable test first — does -ed add a beat? — because it is the part children get wrong and the part that affects fluency. Sorting is the right activity: a pile of -ed words into three columns, read aloud. The voicing distinction between /t/ and /d/ matters less; children produce it correctly anyway.

Learn these first

• The -s and -es ending — -s / -es — Three sounds — /s/, /z/ and /ɪz/ — and the sound before the ending decides which. Children produce all three correctly in speech before anyone teaches them.
• Final blends — -st -nd -mp -nt -ft -lt -sk -lp — Blends at the end of a word. Harder to hear than initial blends, because the final consonant is quieter in ordinary speech.

Related rules

• The -ing ending — -ing — One sound, and the root usually unchanged — but with three spelling changes to recognise: drop the e, double the consonant, or neither.
• Y becomes I before a suffix — y + suffix → i — Happy becomes happier, cry becomes cried, baby becomes babies. A reliable change, and one that explains a lot of otherwise odd-looking words.
• Meaning suffixes: -ful, -less, -ness, -ment — -ful -less -ness -ment -able — Chunks of meaning on the end of a word. Unlike -ed and -ing, they leave the root almost untouched, which makes them the easiest suffixes to read.
