Icono de iDevice Pronunciation

Do you remember the rules for the -ed pronunciation?

There are three different ways of pronouncing the -ed ending. The difference depends on the final sound we pronounce in the infinitive form, if it is voiced (when the vocal cords vibrate) or voiceless (when there is no vibration). You can try this by putting your fingers in your throat when pronouncing a word!

  • When the final sound is voiced, the -ed ending sounds /d/.
  • When the final sound is voiceless, the -ed ending sounds /t/.
  • When the final sound is either /t/ or /d/, then it sounds /Id/.

Decide the -ed pronunciation of these verbs: cooked, started, sailed, wanted, cleaned, asked, added, passed, listened.

/t/
/d/
/Id/

Did you know the origin of the name 'Freetown', the capital city of Sierra Leone?

This country was founded at the end of the 18th century as a home for freed slaves, and this is the reason why its capital was called Freetown. It became a refuge for black people, mainly African slaves from North America who got their freedom and had supported the British in the American War of Independence. Interesting, isn't it?
