SPI English · Spotting Errors
Sentences with No Error
When every check passes, the answer is No error; mark it with confidence instead of inventing a mistake.
Why this matters
Seven of the 33 questions in the bank have No error as the key, five of them on this page and one from the 2022 paper. One is EASY and four are MODERATE here: they are hard because the sentence looks unusual, not because it is wrong.
Concept 1 of 2: Run the checks in order, then trust the result
Definition
The checklist, in the order these pages teach it:
- Verb: does it agree with its subject? Is it a full verb, and passive where the subject is acted on? Is the form after words like 'enjoy' or 'decide' right?
- Tense: does each verb match the time word? Are 'if' sentences and reported questions built correctly?
- Preposition: does each word have its own preposition, and no extra one?
- Small words: who or whom, one comparing form, the right partner for 'no sooner' or 'though', and words that make sense.
- If all four checks pass, the answer is No error.

Concept 2 of 2: Correct English that looks wrong
Definition
Forms that are correct:
- Double possessive: 'a friend of mine', 'a cousin of Ravi's'. Both 'of' and the 's are right together.
- A phrase set off by commas inside a sentence: 'He left home and, holding a bag, walked to the bus.'
- Someone, everyone, nobody take a singular verb: 'Someone has left a bag.'
- Idioms keep their own meaning: 'feet of clay' is a hidden weakness in a person others admire.
- It is well to do something: an older, formal way of saying it is wise to do it.
| Correct form | Why it is right | Example |
|---|---|---|
| double possessive | standard English | She is a friend of my father's. |
| a phrase set off by commas | the commas mark extra information | She went out and, holding an umbrella, crossed the road. |
| someone, everyone, nobody | singular, so the verb takes -s | Nobody knows the answer. |
| feet of clay | an idiom: a hidden weakness in an admired person | The hero turned out to have feet of clay. |
| it is well to | formal for 'it is wise to' | It is well to check the map first. |
