The -ed ending of regular past tense verbs and past participles is pronounced in three different ways: /t/, /d/, or /ɪd/. The correct pronunciation depends entirely on the final sound of the base verb — not the spelling. Mastering this gives speech a much more natural rhythm.
Rule: After voiceless consonant sounds (/p/, /k/, /f/, /s/, /ʃ/, /tʃ/): pronounce -ed as /t/. Examples: stopped /stɒpt/, walked /wɔːkt/, laughed /lɑːft/. After voiced consonant sounds and vowels (/b/, /g/, /v/, /z/, /m/, /n/, /l/, /r/ + all vowels): pronounce -ed as /d/. Examples: called /kɔːld/, played /pleɪd/. After /t/ or /d/ sounds: pronounce -ed as /ɪd/. Examples: waited /ˈweɪtɪd/, needed /ˈniːdɪd/.
Practice
How is the -ed in "washed" pronounced?
Which word has the -ed pronounced /ɪd/?
Put these past tense verbs in the correct group — /t/ sound:
The /ɪd/ pronunciation is the only one that adds an extra syllable to the word. This only happens when the base verb ends in /t/ or /d/: wanted (2 syllables), needed (2 syllables), landed (2 syllables), decided (3 syllables). If the base verb does not end in /t/ or /d/, -ed does NOT add a syllable: "cleaned" is one syllable, not two.
