What is Error Correction?

Error correction means reading a sentence carefully, spotting what is wrong, and rewriting it correctly. Look at these examples:

Incorrect	Incorrect because…	Correct
She go to school.	Wrong verb form	She goes to school.
He are playing in the field.	Subject-verb mismatch	He is playing in the field.
i have a new bag	No capital letter, no full stop	I have a new bag.
Where are you	Missing question mark	Where are you?

A correct sentence is complete, clearly written, starts with a capital letter, and ends with the right punctuation.

Common Types of Errors in Sentences

1. Subject-Verb Agreement Errors

The verb must match the subject. When the subject is he, she, or it (or a single person or thing), we add -s or -es to the verb in simple present tense.

Incorrect	Correct
He go to school.	He goes to school.
She have a pencil box.	She has a pencil box.
Riya walk to the park.	Riya walks to the park.

Rules to remember:

• He / She / It / Name → add -s or -es to the verb. 
• I / We / They / You → keep the verb as it is.

2. Wrong Helping Verb (Is / Are / Am / Has / Have)

Helping verbs must match the subject correctly.

Subject	Correct helping verb
I	am, have
He / She / It / Name	is, has
We / You / They	are, have

Incorrect	Correct
He are reading.	He is reading.
I is ready.	I am ready.
They is happy.	They are happy.

3. Missing Words

Sometimes a word, often a helping verb or preposition, is left out, making the sentence incomplete.

Incorrect	Missing word	Correct
She playing in the park.	is	She is playing in the park.
We are going playground.	to the	We are going to the playground.
Arjun coming home.	is	Arjun is coming home.

4. Capitalisation Errors

Every sentence must begin with a capital letter. Names of people, places, and specific things (proper nouns) also need capital letters.

Incorrect	Correct
i am ready.	I am ready.
my name is priya.	My name is Priya.
we live in delhi.	We live in Delhi.

5. Punctuation Errors

Every sentence must end with the correct punctuation mark. Statements end with a full stop (.), questions end with a question mark (?), and exclamations end with an exclamation mark (!).

Incorrect	Correct
Where are you	Where are you?
She is my friend	She is my friend.
What a lovely day	What a lovely day!

6. Word Order Errors

Words in an English sentence follow a pattern: Subject → Verb → Object/Rest of sentence.

Incorrect	Correct
Very happy she is.	She is very happy.
Playing are they outside.	They are playing outside.
To school goes Arjun early.	Arjun goes to school early.

How to Correct a Sentence: A Simple Checklist

Before marking a sentence correct, run through these four checks:

1. Does the verb match the subject? He goes (not go). They are (not is).
2. Are any words missing? Read the sentence aloud. If it sounds incomplete, a word is likely missing.
3. Does it start with a capital letter and end with the right punctuation? Statement → full stop. Question → question mark. Exclamation → exclamation mark.
4. Are the words in the right order? Subject first, then verb, then the rest.
