‘Ed’ can make different sounds.
Sometimes it sounds like ‘id’
Sometimes it sounds like ‘d’
Sometimes it sounds like ‘t’
So how do we know when to use these different sounds
Listen and practise
All these ‘ed’ endings make the ‘id’ sound. Can you guess the rule
Look at the last letter of each verb.
Hint!
x
Show answer
If the verb ends in a ‘t’ or a ‘d’, the ‘ed’ ending makes a ‘id’ sound. This adds one extra syllable. Now practice the words!

No!
Listen and practise
All these ‘ed’ endings make the ‘t’ sound. Can you guess the rule
Show answer
If the verb ends in a sound that doesn’t vibrate your voice box, we use the ‘t’ ending. This adds no extra syllables.

Do you find the ‘t’ ending difficult
Many learners do.
Imagine you’re playing the drums!
Practice these sounds as if you were paying imaginary drums.
‘K’
and
‘T’
Then practice them together:
‘K’ - ‘T’ as fast as you can.
And then finally practice saying them at the end of a word: Wal-k-t
