Add -ed to the verbs, put them in the correct column and read them out. arrive, close, help, want, hurry, look, watch, clean, cook, regret, rob, visit, add, push, start, live, end, wait, count, like, travel, tidy, laughter, finish, kiss, post, change, open. /i'd/ /t/ after /t/, /d/ /k/

To correctly pronounce the -ed ending in English, the sound depends on the final sound of the base verb. Note: "laughter" is a noun and cannot take an -ed ending, so it is excluded. 1. /ɪd/ (After /t/ or /d/ sounds) The suffix is pronounced as an extra syllable.

• Add: added
• Count: counted
• End: ended
• Post: posted
• Regret: regretted (double 't' per Cambridge Dictionary spelling rules)
• Start: started
• Visit: visited
• Wait: waited
• Want: wanted

2. /t/ (After voiceless sounds: /p, k, f, s, ʃ, tʃ/) The suffix sounds like a sharp "t".

• Cook: cooked
• Finish: finished
• Help: helped
• Kiss: kissed
• Like: liked
• Look: looked
• Push: pushed
• Watch: watched

3. /d/ (After voiced sounds: /b, g, v, z, l, m, n, r/ and vowels) The suffix sounds like a soft "d".

• Arrive: arrived
• Change: changed
• Clean: cleaned
• : closed
• Hurry: hurried (change 'y' to 'i' per Oxford Learner's Dictionaries)
• Live: lived
• Open: opened
• Rob: robbed (double 'b')
• Tidy: tidied
• Travel: travelled (UK) or traveled (US)

To practice, try reading the /ɪd/ column focusing on the extra syllable, then contrast the /t/ and /d/ columns where the vowel remains silent.
