1. Common Errors with Is, Am and Are

Is, am and are are present forms of the verb be. They are used to describe identity, condition, location and ongoing actions.

Subject	Correct form	Example
I	am	I am ready.
He / She / It	is	She is happy.
You / We / They	are	They are busy.
Plural nouns	are	The students are here.
Singular nouns	is	The student is here.

Common mistakes and corrections

Incorrect: I is a student.

Correct: I am a student.

Incorrect: She are my friend.

Correct: She is my friend.

Incorrect: They is playing.

Correct: They are playing.

Incorrect: He am working.

Correct: He is working.

Remember the difference

• Is: He is at home.
• Am: I am learning English.
• Are: We are ready.

Important: Do not use is, am or are before the base verb to form a simple present sentence. Say “She works,” not “She is work.” For an ongoing action, use “She is working.”

हिंदी में समझें: I के साथ am, he/she/it के साथ is और you/we/they के साथ are का प्रयोग होता है। वाक्य बनाते समय subject को पहचानना सबसे ज़रूरी है।

2. Common Errors with Has, Have and Had

Has, have and had can express possession and also work as helping verbs in perfect tenses.

Subject or time	Correct form	Example
He / She / It	Has	She has a car.
I / You / We / They	Have	They have a plan.
All subjects in the past	Had	He had a bicycle.

Common mistakes and corrections

Incorrect: He have a new phone.

Correct: He has a new phone.

Incorrect: They has two children.

Correct: They have two children.

Incorrect: I has completed my work.

Correct: I have completed my work.

Incorrect: She have finished her homework.

Correct: She has finished her homework.

Has and have as helping verbs

• He has eaten breakfast.
• We have completed the project.
• They have arrived.

Had for past situations

• I had a small shop.
• She had finished the work before noon.
• We had already left when he arrived.

Remember: In the present perfect tense, use has/have + past participle (third form). For example, “She has written a letter,” not “She has wrote a letter.”

हिंदी में समझें: वर्तमान समय में singular third-person subject के साथ has और अन्य सामान्य subjects के साथ have आता है। Had का प्रयोग past में सभी subjects के साथ किया जा सकता है।

3. Do, Does and Did: Common Mistakes

Do, does and did are commonly used to form questions and negative sentences in English simple tenses. They can also be used as main verbs.

Form	Subjects	Example
Do	I, you, we, they	Do you work here?
Does	He, she, it	Does she work here?
Did	All subjects in the past	Did they call you?

Important rule: Use the base verb after do, does and did

Incorrect: Does he works here?

Correct: Does he work here?

Incorrect: She don't like coffee.

Correct: She doesn't like coffee.

Incorrect: Did you went to school?

Correct: Did you go to school?

Incorrect: He doesn't knows me.

Correct: He doesn't know me.

Question and negative patterns

Question: Do + subject + base verb?

Do you speak English?

Negative: Subject + do/does not + base verb.

She does not speak French.

Past question: Did + subject + base verb?

Did he call you yesterday?

Remember: Once does or did is used as an auxiliary, the main verb stays in its base form. Do not add -s or use the past form again.

हिंदी में समझें: Does के बाद verb में s/es नहीं लगाते। Did के बाद भी verb की first form आती है। इसलिए “Did you went?” नहीं, “Did you go?” सही है।

4. Confusing Was and Were

Was and were are past forms of the verb be. The correct choice depends on the subject and the sentence structure.

Subject	Correct form	Example
I	Was	I was tired.
He / She / It	Was	He was late.
Singular noun	Was	The room was clean.
You / We / They	Were	They were happy.
Plural noun	Were	The children were outside.

Common mistakes and corrections

Incorrect: I were busy yesterday.

Correct: I was busy yesterday.

Incorrect: They was at home.

Correct: They were at home.

Incorrect: She were studying.

Correct: She was studying.

Incorrect: We was waiting for you.

Correct: We were waiting for you.

Special use: If I were

In hypothetical or unreal situations, English commonly uses were with I, he, she and it.

If I were rich, I would travel around the world.

If she were here, she could help us.

In ordinary past statements, use “I was.” In hypothetical expressions such as “If I were you,” were is the standard form.

हिंदी में समझें: सामान्य past sentences में I/he/she/it के साथ was और you/we/they के साथ were आता है। लेकिन काल्पनिक स्थिति में “If I were you” जैसे वाक्य में were का प्रयोग होता है।

5. Incorrect Use of Articles

English has three articles: a, an and the. Choosing the correct article depends on the meaning and context of the noun.

A and An

Use a before a singular countable noun beginning with a consonant sound. Use an before a singular countable noun beginning with a vowel sound.

Incorrect: She is an teacher.

Correct: She is a teacher.

Incorrect: He ate a apple.

Correct: He ate an apple.

Correct: He is an honest man.

Correct: She studies at a university.

ध्यान दें: Article का चुनाव spelling से नहीं, शुरुआती sound से होता है। Honest में h silent है, इसलिए an आता है। University की शुरुआत “yu” sound से होती है, इसलिए a आता है।

Using The

Use the when referring to a particular or identifiable person, thing or group.

Incorrect: Sun rises in east.

Correct: The sun rises in the east.

Incorrect: Please close door.

Correct: Please close the door.

When no article is needed

Do not automatically place an article before every noun. Plural nouns and uncountable nouns can be used without an article when speaking generally.

Incorrect: The books are useful for everyone. (when speaking about books generally)

Correct: Books are useful for everyone.

Incorrect: The information is important. (when speaking about information generally)

Correct: Information is important.

Important: “The books are useful” is also correct when you mean specific books. Articles depend on meaning, not just a memorised rule.

हिंदी में समझें: A और An का प्रयोग सामान्यतः singular countable nouns के साथ होता है। The का प्रयोग किसी विशेष या पहचान में आने वाली चीज़ के लिए होता है। General meaning में कई बार article नहीं लगाया जाता।

6. Incorrect Use of Prepositions

Prepositions show relationships involving time, place, direction and other connections. Some prepositions are difficult because English expressions do not always match Hindi word-for-word.

Common preposition mistakes

Incorrect	Correct
Discuss about the problem	Discuss the problem
Enter into the room	Enter the room
Married with her	Married to her
Good in English	Good at English
Depend of someone	Depend on someone
Listen music	Listen to music
Wait me	Wait for me

More examples

Incorrect: I am waiting you.

Correct: I am waiting for you.

Incorrect: She is interested on music.

Correct: She is interested in music.

Incorrect: He is afraid from dogs.

Correct: He is afraid of dogs.

Remember common combinations

• Interested in something
• Good at something
• Afraid of something
• Depend on someone or something
• Listen to someone or something
• Wait for someone or something
• Belong to someone

Some verbs do not need a preposition after them. For example, “discuss something” and “enter a room” are standard constructions. Avoid adding a preposition just because a similar Hindi expression contains one.

हिंदी में समझें: कई English verbs और adjectives के साथ एक निश्चित preposition आता है। इन्हें केवल शब्द-दर-शब्द अनुवाद करके नहीं, बल्कि पूरे phrase के रूप में सीखना बेहतर है।

7. Incorrect Verb Forms

English verbs have different forms. Choosing the wrong form after a helping verb, modal verb or particular expression is a common source of grammatical errors.

Common verb-form mistakes

Incorrect	Correct	Reason
She has went.	She has gone.	Has + past participle
He did not came.	He did not come.	Did + base verb
I can to swim.	I can swim.	Modal + base verb
She enjoys to dance.	She enjoys dancing.	Enjoy + gerund
He is knowing the answer.	He knows the answer.	Know is normally a state verb

Learn the three main verb forms

Base form	Past form	Past participle
Go	Went	Gone
Write	Wrote	Written
Eat	Ate	Eaten
Speak	Spoke	Spoken
Take	Took	Taken
See	Saw	Seen
Do	Did	Done

More useful patterns

She wants to learn English.

They decided to leave early.

He avoids wasting time.

You should practise every day.

Tip: Learn verbs together with their common patterns: want to do, enjoy doing, avoid doing, can do and should do. This makes correct sentence formation easier.

हिंदी में समझें: हर helping verb के बाद एक ही प्रकार की verb form नहीं आती। जैसे has के बाद third form, did के बाद first form और can/should के बाद base form आती है।

8. Double Negatives and Other Sentence Errors

A double negative occurs when two negative expressions are used in a way that creates an unintended or non-standard negative construction.

Double negative examples

Incorrect in standard English: I don't know nothing.

Correct: I don't know anything.

Incorrect in standard English: She didn't say nothing.

Correct: She didn't say anything.

Incorrect in standard English: He never does nothing.

Correct: He never does anything.

Other common sentence errors

Incorrect: Myself Rahul.

Correct: I am Rahul. / My name is Rahul.

Incorrect: I am having two brothers.

Correct: I have two brothers.

Incorrect: He is more taller than me.

Correct: He is taller than me.

Incorrect: Because I was tired, so I slept early.

Correct: Because I was tired, I slept early.

Also correct: I was tired, so I slept early.

Sentence fragments

A sentence fragment is an incomplete group of words presented as a complete sentence.

Incomplete: Because I missed the bus.

Complete: Because I missed the bus, I arrived late.

Run-on sentences

A run-on sentence joins independent clauses incorrectly, without suitable punctuation or a linking word.

Incorrect: I was tired I went to bed.

Correct: I was tired, so I went to bed.

Also correct: I was tired. I went to bed.

Double negatives can be used intentionally in some dialects and informal varieties of English. This lesson focuses on standard written English and the forms expected in formal communication and most grammar exercises.

हिंदी में समझें: Standard English में एक ही negative meaning के लिए अनावश्यक रूप से दो negative words का प्रयोग न करें। साथ ही, वाक्य में subject और complete thought होना चाहिए।

9. Common Mistakes Made by Hindi Speakers

Hindi and English have different grammar structures. When learners translate Hindi sentences word by word into English, the result may sound unnatural or grammatically incorrect.

These examples are useful learning points for Hindi-speaking learners. They are not mistakes made by every Hindi speaker; individual learning needs vary.

Common translation-related errors

Incorrect English	Natural or correct English
My age is 25 years.	I am 25 years old.
He is having a car.	He has a car.
What is your good name?	What is your name?
Open the light.	Turn on the light.
Close the fan.	Turn off the fan.
I passed out from college in 2024.	I graduated from college in 2024.
Return back soon.	Return soon.
He is my cousin brother.	He is my cousin.

More examples for daily conversation

Less natural: I am going to home.

Natural: I am going home.

Incorrect: I have one doubt.

More natural in many contexts: I have a question.

Incorrect: He is elder than me.

Correct: He is older than me.

Use “elder” mainly before a noun in family relationships: “my elder brother.”

Incorrect: I am discussing about my work.

Correct: I am discussing my work.

Think in English instead of translating every word

• Learn complete phrases rather than isolated words.
• Notice how native and proficient speakers form everyday sentences.
• Practise common expressions in real situations.
• Check whether a sentence sounds natural, not only whether each word is translated correctly.
• Read and listen to clear, reliable English regularly.

Learning tip: “What is your good name?” is understood in some Indian contexts, but “What is your name?” is the standard expression in international English.

हिंदी में समझें: हिंदी से अंग्रेज़ी में शब्द-दर-शब्द अनुवाद करने से कई बार वाक्य unnatural बन जाता है। पूरे English phrases और sentence patterns सीखने से बोलने और लिखने में सुधार होता है।

Daily Grammar Practice Plan

You do not need to study every grammar rule at once. Spend a little time each day correcting your own sentences.

Time	Activity
5 minutes	Review one grammar rule.
5 minutes	Write five sentences using that rule.
5 minutes	Find and correct mistakes in your sentences.
5 minutes	Speak the corrected sentences aloud.

Daily target: Learn one useful correction and use it in a real conversation.

हिंदी में समझें: रोज़ केवल 20 मिनट अभ्यास करें। एक नियम सीखें, पाँच वाक्य बनाएँ, गलतियाँ सुधारें और फिर उन वाक्यों को बोलकर अभ्यास करें।

Final Learning Tips

• Do not memorise only the incorrect and correct sentences; understand the grammar rule behind each correction.
• Pay special attention to helping verbs and the verb forms that follow them.
• Keep a small notebook of mistakes you personally make.
• Practise writing and speaking with corrected sentence patterns.
• Review your mistakes regularly instead of trying to learn everything in one day.

अंतिम बात: गलतियाँ करना सीखने की प्रक्रिया का हिस्सा है। जब आप अपनी गलतियों को पहचानकर सही वाक्य का अभ्यास करते हैं, तो आपकी English धीरे-धीरे अधिक स्पष्ट और स्वाभाविक बनती है।
