past -ed
Core Rule
The -ed past tense marks regular verbs, but pronunciation follows sounds, not letters. Three patterns apply: /t/ after voiceless sounds, /d/ after voiced sounds or vowels, and /ɪd/ after /t/ or /d/.
Articulation Guide
/t/: tongue touches alveolar ridge, air released without voicing; /d/: same placement with voicing; /ɪd/: short /ɪ/ plus /d/.
Word Analysis
alleged ends in voiced /dʒ/ → /d/; coloured ends in voiced /r/ → /d/; conceited ends in /t/ → /ɪd/.
Pitfalls
Spelling variants (coloured/colored) don’t change sound rules; avoid reading every -ed as /ɪd/.
Phonics Breakdown
Hear final sound → check voicing → choose /t/, /d/, or /ɪd/; /ɪd/ adds a beat
Sound Reference
- Decide by final sound, not spelling
- Treat /ɪd/ as an extra syllable
Common Mistakes
Reading all -ed as /ɪd/
Ignoring voicing contrast
