4. Irregular Verb Reference Table

The table below groups more than two hundred common irregular verbs by pattern, since recognizing the pattern is faster than memorizing each verb in isolation. "Choose the correct past participle" and "identify the error in verb form" questions draw heavily and repeatedly from exactly this list. A new closing subsection, 4.6, isolates twenty-five irregular-verb pairs that aspirants most often mix up, each with a worked wrong/fix example.

4.1 Group A — No Change (base = past = past participle)

*Note: "bind" does not belong to Group A — it is listed in Group C (bind–bound–bound); it is flagged here only as a common mistaken guess, since learners sometimes assume it patterns like "bid."

Note on "read": the three forms are spelled identically but pronounced differently — the past simple and past participle "read" rhyme with "red," not with the base form. This is a common pronunciation (not spelling) trap in listening-based sections and viva-style interviews.

4.2 Group B — Vowel-Change Pattern (i → a → u)

4.3 Group C — Past & Past Participle Identical (base changes once)

4.4 Group D — All Three Forms Different

4.5 Group E — Come = Become Pattern (base = past participle, past simple different)

4.6 Commonly Confused Irregular Forms

The pairs below are not simply "learn the table" items — they are the specific confusions that repeatedly cost marks even among candidates who have memorized the table above, because the two forms in each pair look similar, sound similar, or belong to verbs that are conceptually close. Each pair includes a wrong/fix example.

1. lay vs lie — "lay" is transitive (to place something down: lay–laid–laid); "lie" is intransitive (to recline: lie–lay–lain). Wrong: She was laying on the sofa all afternoon. Fix: She was lying on the sofa all afternoon.

2. rise vs raise — "rise" is intransitive (rise–rose–risen); "raise" is transitive and needs an object (raise–raised–raised). Wrong: The flag raised slowly as the anthem played. Fix: The flag rose slowly as the anthem played.

3. hang (hanged) vs hang (hung) — "hanged" applies only to execution by hanging; "hung" is used for every other meaning. Wrong: The mirror was hanged crookedly on the wall. Fix: The mirror was hung crookedly on the wall.

4. sit vs seat — "sit" is intransitive (sit–sat–sat); "seat," meaning to cause someone to sit, is transitive and regular (seat–seated–seated). Wrong: The host sat the guests according to seniority. Fix: The host seated the guests according to seniority.

5. fell (past of "fall") vs fell/felled (to cut down a tree) — the same spelling "fell" is both the irregular past simple of "fall" and a separate, regular transitive verb meaning to cut down. Wrong: The loggers felled the tree fell to the ground. (confusing usage) Fix: The loggers felled the tree, and it fell to the ground. ("felled" = they cut it down; "fell" = it dropped)

6. broke vs broken — "broke" is the past simple, used alone as the main verb; "broken" is the past participle, used only after "has/have/had" or "be." Wrong: He has broke the record for the fastest lap. Fix: He has broken the record for the fastest lap.

7. began vs begun — parallel confusion: "began" stands alone; "begun" needs an auxiliary. Wrong: The ceremony has began without the chief guest. Fix: The ceremony has begun without the chief guest.

8. drank vs drunk — "drank" stands alone as past simple; "drunk" needs "has/have/had" or "be." Wrong: She has drank three cups of coffee already. Fix: She has drunk three cups of coffee already.

9. sang vs sung — same pattern as above. Wrong: The choir has sang beautifully at every event this year. Fix: The choir has sung beautifully at every event this year.

10. rang vs rung — same pattern. Wrong: Someone has rang the doorbell twice already. Fix: Someone has rung the doorbell twice already.

11. ran vs run — same pattern. Wrong: He has ran the full marathon three times. Fix: He has run the full marathon three times.

12. saw vs seen — one of the single most frequently tested pairs in SSC error-spotting. Wrong: I have saw that movie already. Fix: I have seen that movie already.

13. did vs done — same pattern. Wrong: She has did all the paperwork herself. Fix: She has done all the paperwork herself.

14. went vs gone — same pattern. Wrong: They have went to the market already. Fix: They have gone to the market already.

15. ate vs eaten — same pattern. Wrong: He has already ate his lunch. Fix: He has already eaten his lunch.

16. gave vs given — same pattern. Wrong: She has gave her final answer. Fix: She has given her final answer.

19. spoke vs spoken — same pattern. Wrong: He has spoke to the manager about the transfer. Fix: He has spoken to the manager about the transfer.

20. threw vs thrown — same pattern. Wrong: The bowler has threw the ball wide twice. Fix: The bowler has thrown the ball wide twice.

21. drove vs driven — same pattern. Wrong: She has drove this route many times before. Fix: She has driven this route many times before.

22. chose vs chosen — same pattern. Wrong: The panel has chose the winning entry. Fix: The panel has chosen the winning entry.

23. knew vs known — same pattern. Wrong: He has knew about the merger for weeks. Fix: He has known about the merger for weeks.

24. grew vs grown — same pattern. Wrong: The company has grew rapidly this year. Fix: The company has grown rapidly this year.

25. shook vs shaken — same pattern. Wrong: The scandal has shook public confidence badly. Fix: The scandal has shaken public confidence badly.

The underlying rule behind pairs 6 through 25: in every one of these twenty pairs, the past simple form (broke, began, drank, sang, rang, ran, saw, did, went, ate, gave, took, wrote, spoke, threw, drove, chose, knew, grew, shook) is used only as a standalone main verb with no auxiliary, while the past participle form (broken, begun, drunk, sung, rung, run, seen, done, gone, eaten, given, taken, written, spoken, thrown, driven, chosen, known, grown, shaken) is used only after an auxiliary — "has/have/had" for the perfect tenses, or a form of "be" for the passive voice. Once this single rule is automatic, all twenty of these "confused pairs" collapse into one pattern rather than twenty separate facts to memorize.
