One Syllable:
* If the "-ed" is pronounced as a single sound (like the "t" in "walked" or the "d" in "played"), then it's just one syllable.
* This is common in words where the final consonant sound before the "-ed" is a "t" or a "d" sound.
Two Syllables:
* If the "-ed" is pronounced as a separate syllable (like the "id" in "wanted"), then it's two syllables.
* This happens when the final consonant sound before the "-ed" is not a "t" or a "d" sound.
Examples:
One Syllable:
* walked
* played
* stopped
* jumped
* talked
Two Syllables:
* wanted
* hated
* needed
* painted
* decided
In short, listen to how the word is pronounced. If the "-ed" sounds like a single sound, it's one syllable. If it sounds like a separate syllable, it's two syllables.
