18. What are the rules?
There are three rules we should take into account to know how to
pronounce the –ed ending:
Rule 1: If a present tense verb ends with the sound of a voiced
consonant or a vowel sound, the pronunciation in past tense is /d/
Rule 2: If the present tense verb ends with the sound of a voiceless
consonant sound (f, k, s, x, sh, ch, or p), the pronunciation in past tense
is /t/
Rule 3: If the present tense verb ends with the sound of /t/ or /d/
consonant sound, the pronunciation in past tense is always /id/
Note: it’s the ending sound, not spelling that determines pronunciation.
