ed /ɪd/

Rule Core

Weak -ed pronunciation refers to -ed being pronounced as /ɪd/, adding a light extra syllable. This occurs when the base word ends in /t/ or /d/. The added vowel prevents difficult consonant clusters and supports natural English rhythm.

Articulation Guide

Start with a short, relaxed /ɪ/: tongue low and loose, lips neutral. Immediately release into a soft /d/ with minimal stop. The syllable is quick and unstressed; never stretch it into /iːd/.

Word Analysis

• frightened /ˈfraɪtənd/: frighten ends in /t/, so -ed becomes /ɪd/.
• interested /ˈɪntrəstɪd/: interest ends in /t/; -ed forms a weak syllable, and internal vowels may reduce.

Pitfalls

Do not generalize. If the base does not end in /t/ or /d/, -ed is pronounced /t/ or /d/, as in watched or played.
