1 Three possible pronunciations
In English, the ending -ed in the simple past and the past participle is not always pronounced the same way. There are three main pronunciations:
/d/ → waved
/t/ → walked
/ɪd/ (écrit /id/ pour simplifier) → visited
Good news: you do not need to learn long rules to be understood.
With a simple strategy, you can usually find the correct pronunciation.
