It’s difficult to know how to pronounce ‘ed’ in English, because it’s pronounced in three different ways. It depends on the letter before.
The three ways are:
1: ‘id’ (like in painted ‘paint-id’)
2: ‘t’ (like in ‘hoped’)
3: ‘d’ (like in ‘played’)
1: ‘id’
The most important thing to remember is this:
If the verb has a ‘d’ or a ‘t’ sound before ‘ed’ you need to pronounce ‘id’. If it doesn’t, don’t pronounce an extra syllable.
Be careful! It’s the sound, not the letter: ‘decided’ is pronounced ‘decid-id’ even though it ends in ‘e’, because we don’t say the ‘e’, so the last sound is ‘d’.
So for example: ATTENZIONE!!! LA PRONUNCIA INDICATA TRA PARENTESI E’ QUELLA ITALIANA, NON RISPETTA I SIMBOLI FONETICI
wanted (uont-id)
ended (end-id)
decided (desid-id)
admitted (admit-id)
suggested (saggest-id)
recommended (recommend-id)
hated (heit-id)
intended (intend-id)
started (start-id)
2: ‘t’
If the word before ‘ed’ ends in the sounds ‘p’, ‘f’, ‘s’, ‘ch’, ‘sh’, ‘k’, then ‘ed’ is pronounced ‘t’.
So: ATTENZIONE!!! LA PRONUNCIA INDICATA TRA PARENTESI E’ QUELLA ITALIANA, NON RISPETTA I SIMBOLI FONETICI
‘p’ stopped (stop-t)
‘f’ laughed (laf-t)
‘s’ promised (promis-t)
‘ch’ watched (uoch-t)
‘sh’ finished (finisch-t)
‘k’ walked (uook-t)
3: ‘d’
For all other words, ‘ed’ is pronounced ‘d’: ATTENZIONE!!! LA PRONUNCIA INDICATA TRA PARENTESI E’ QUELLA ITALIANA, NON RISPETTA I SIMBOLI FONETICI
allowed (allou-d)
cried (crai-d)
enjoyed (engioi-d)
cleaned (clin-d)
imagined (imegin-d)
