Regular verbs all end with -ed.
To help you answer the question, find the sound that comes in front of the -ed ending.
For example, in the verb helped, /p/ is the sound right before the -ed. Put your fingertips on your throat and say /p/. There is no vibration. /p/ is a voiceless sound. If the sound before -ed is voiceless, -ed sounds like a /t/.
Some other examples of voiceless sounds are /k/ /sh/ /f/
The -ed ending would sound like a /t/ when we say the verbs: asked, hiked, washed, fished, laughed, stuffed.
In contrast, look at the verb owed. The /ow/ sound like the vowel sound /o/. Put your fingers against your throat. Your throat vibrates. The sound is voiced. If the sound before -ed is voiced, the -ed sound like a /d/.
Some other examples of voiced sounds are /m/, /n/, all vowels, /g/, and /z/.
The -ed ending would sound like a /d/ when we say the verbs: hummed, named, planned, banned, payed, sighed, hugged, gagged, buzzed, and raised.
The final sound, the extra syllable /ɪd/, happens when the sound right before the -ed ending is /t/ or /d/.
Read the paragraph below. Find all of the -ed verbs. Find the sound right before the -ed ending. Do you need to pronounce it as /t/, /d/, or /Id/?
Yesterday, it started to rain. I opened my umbrella and looked for shelter. I wanted to stay dry. I needed to look good for work. I entered a building and watched the rain come down. It poured for a long time. People looked very wet. They splashed through the puddles. They seemed grumpy about the weather. They frowned. I waited until it stopped raining. I used my phone while I waited. I texted my friends. I practiced pronunciation. I watched videos on YouTube.
(The answers are below)
looked, watched, splashed, practiced
opened, entered, poured, seemed, frowned, used
started, wanted, needed, waited, texted
