について -ed ending in regular past tense verbs and past participles has three different pronunciations: /ɪd/, /t/, 、または /d/. The sound depends on the final sound of the base verb before -ed is added. The most important rule to remember is that you only add an extra syllable (the /ɪd/ sound) when the base verb ends with a /t/ または /d/ sound. For all other verbs, the -ed ending does not add an extra syllable; it simply blends into the final sound of the verb, becoming either /t/ または /d/. Mastering these rules will significantly improve your spoken English clarity and naturalness.
Why is -ed Pronunciation Important?
Correct pronunciation of -ed endings makes your English sound more natural and easier to understand. Mispronouncing these common endings can sometimes confuse listeners or make your speech sound less fluent.
It’s a key part of speaking clearly, especially when talking about past events or using passive voice constructions.
The Three Sounds of -ed Endings
について -ed ending has three distinct sounds. The sound you use depends on the last sound of the verb before you add -ed.
- /ɪd/ （または /əd/): This sound adds an extra syllable.
- /t/: This sound does not add an extra syllable.
- /d/: This sound also does not add an extra syllable.
Rule 1: The /ɪd/ Sound (Extra Syllable)
This is the easiest rule to remember because it’s the only one that adds an extra syllable to the word.
- Use the /ɪd/ sound when the base verb ends with a /t/ sound or a /d/ sound.
- Think of verbs like want (ends in /t/) or need (ends in /d/).
- When you add -ed, they become want/ɪd/ そして need/ɪd/.
Rule 2: The /t/ Sound
This sound does not add an extra syllable. It’s used after voiceless sounds.
- Use the /t/ sound when the base verb ends with a voiceless consonant sound.
- Voiceless sounds are made without vibrating your vocal cords. Try saying /p/, /k/, /f/, /s/, /ʃ/ (like in wash), or /tʃ/ (like in watch).
- For example, walk (ends in /k/) becomes walk/t/. Watch (ends in /tʃ/) becomes watch/t/.
Rule 3: The /d/ Sound
This sound also does not add an extra syllable. It’s used after voiced sounds.
- Use the /d/ sound when the base verb ends with a voiced consonant sound or a vowel sound.
- Voiced sounds are made by vibrating your vocal cords. Try saying /b/, /g/, /v/, /z/, /ʒ/ (like in measure), /dʒ/ (like in change), /m/, /n/, /ŋ/ (like in sing), /l/, /r/, or any vowel sound.
- For example, play (ends in a vowel sound) becomes play/d/. Love (ends in /v/) becomes love/d/.
Voiced vs. Voiceless Sounds: A Quick Guide
To tell if a sound is voiced or voiceless, put your hand on your throat and make the sound.
- Voiced sounds: You will feel a vibration in your throat. Examples: /b/, /d/, /g/, /v/, /z/, /m/, /n/, and all vowel sounds.
- Voiceless sounds: You will not feel a vibration. Examples: /p/, /t/, /k/, /f/, /s/, /h/.
This distinction is crucial for applying rules 2 and 3 correctly.
| Ending Sound of Base Verb | -ed Pronunciation | Example Verb | 発音 |
|---|---|---|---|
| /t/ または /d/ | /ɪd/ (extra syllable) | want | want/ɪd/ |
| Voiceless consonant (e.g., /p/, /k/, /f/, /s/, /ʃ/, /tʃ/) | /t/ (no extra syllable) | walk | walk/t/ |
| Voiced consonant (e.g., /b/, /g/, /v/, /z/, /m/, /n/) or Vowel sound | /d/ (no extra syllable) | play | play/d/ |

練習
スペイン語話者がよく犯す間違い
Spanish speakers often make two main mistakes with -ed endings:
- Adding an extra syllable to all -ed verbs: It’s common to pronounce words like walked as *walk-ed* (/wɔːkɪd/) instead of walk/t/ (/wɔːkt/). Remember, the /ɪd/ sound is only for verbs ending in /t/ または /d/.
- Confusing /t/ そして /d/ sounds: Sometimes, the distinction between look/t/ そして love/d/ can be difficult. Focus on whether the final sound of the base verb is voiced or voiceless. Practice feeling the vibration in your throat to help.
よくある質問
How many ways can I pronounce -ed?
There are three ways to pronounce the -ed ending: /ɪd/, /t/, 、および /d/.
What is a ‘voiceless’ sound?
A voiceless sound is made without vibrating your vocal cords. If you put your hand on your throat, you won’t feel any movement when you make a voiceless sound, like /p/ または /s/.
Why do some -ed verbs have an extra syllable?
An extra syllable (the /ɪd/ sound) is added only when the base verb already ends with a /t/ または /d/ sound. This makes the pronunciation clearer and easier, as in start/ɪd/ または decid/ɪd/.
Does this apply to all past tense verbs?
These rules apply to regular past tense verbs and past participles. Irregular verbs, like go (went) or eat (ate), have different forms and do not use the -ed ending.
How can I practice -ed pronunciation?
Listen carefully to native speakers, record yourself saying verbs with -ed, and pay attention to the final sound of the base verb. The interactive exercise in this lesson is a great way to practice identifying the correct sounds.
