This section provides detailed step-by-step instructions on how to use 21 different types of conjunctions to combine sentences. Each conjunction type has specific rules that you must follow to create grammatically correct sentences.
Important: Master these rules for perfect sentence combining in your RBSE exams!
When both sentences have the SAME subject:
• His father is a teacher. He is a poet.
→ His father is both a teacher and a poet.
• Ram is a player. He is a student.
→ Ram is both a player and a student.
When both sentences have DIFFERENT subjects:
• Rajesh was a student. Sita was a student.
→ Both Rajesh and Sita were students.
• English is an important language. Hindi is an important language.
→ Both English and Hindi are important languages.
When both sentences have the SAME subject:
• Sita came to my house. She cooked food for me.
→ Sita came to my house and cooked food for me.
• Ram is going to Jaipur. He is going to Ajmer.
→ Ram is going to Jaipur and Ajmer.
When both sentences have DIFFERENT subjects:
• Sarita likes coffee. Saroj likes coffee.
→ Sarita and Saroj like coffee.
• Ram is my brother. Shyam is my brother.
→ Ram and Shyam are my brothers.
When both sentences have the SAME subject:
• Ram plays cricket. He plays hockey.
→ Ram plays not only cricket but also hockey.
• Ram saw a tiger. He saw a lion.
→ Ram saw not only a tiger but also a lion.
When both sentences have DIFFERENT subjects:
• My brother helps me in my work. My teacher helps me in my work.
→ Not only my brother but also my teacher helps me in my work.
• Saroj lives in this house. Narendra lives in this house.
→ Not only Saroj but also Narendra lives in this house.
Same rules as "Not only - but also" but:
• Hari must work hard. He must play some game.
→ Hari must either work hard or play some game.
• He is going to Jaipur. She is going to Jaipur.
→ Either he or she is going to Jaipur.
Important: Remove "not/do not/does not/did not" from sentences because "neither...nor" is already negative.
Follow the same rules as "Either - or" but use "neither" and "nor"
• He does not play football. He does not play hockey.
→ He plays neither football nor hockey.
• The teachers did not play hockey. The students did not play hockey.
→ Neither the teachers nor the students played hockey.
Note: If "does not" appears, remove it and add s/es to the verb. If "did not" appears, remove it and use V2.
• Ram is very tired. He cannot walk anymore.
→ Ram is so tired that he cannot walk anymore.
• He is quite clever. You understand well.
→ He is so clever that you understand well.

→ The question is too hard for her to solve.
• The print was very small. My grandfather could not read it.
→ The print was too small for my grandfather to read.
Note: If the second subject is a noun (Ram, Naresh, My father), keep it as is after "for". Only change pronouns to object form.
• The news is too good to be true.
→ The news is so good that it cannot be true.
• My mother was too old to run fast.
→ My mother was so old that she could not run fast.

→ The box was so heavy that Ram could not lift.
Important: The verb agrees with the subject BEFORE "as well as"

• He worked hard. He failed in the examination.
→ He worked hard but he failed in the examination.
• She tried her best. She could not succeed.

Alternative: You can also put "though/although" between the two sentences with a comma before it

→ Although he is poor, he is honest.
→ He is poor, though he is honest.
• He worked hard. He failed.
→ Though he worked hard, he failed.
→ He worked hard, though he failed.
These words show strong contrast and are interchangeable:
For However/Nevertheless: Use a semicolon (;) instead of comma, then add the word
• He is poor. He is honest.
→ He is poor, yet he is honest.
→ He is poor, still he is honest.
→ He is poor; however, he is honest.
→ He is poor; nevertheless, he is honest.
• She worked very hard. She failed in the exam.
→ She worked very hard, yet she failed in the exam.
→ She worked very hard; however, she failed in the exam.
Note: The second sentence must be a result or consequence of the first
• He worked hard. He passed the examination.
→ He worked hard so he passed the examination.
→ He worked hard; therefore, he passed the examination.
• It was raining heavily. We stayed at home.

→ Work hard otherwise you will fail.
• Hurry up. You will miss the train.
→ Hurry up or you will miss the train.
→ Hurry up else you will miss the train.
• Study regularly. You will not pass the exam.
→ Study regularly or you will not pass the exam.
Used to show reason/cause (all three are interchangeable):
Alternative: You can also put these conjunctions between the two sentences
• He was ill. He could not attend the meeting.
→ Since he was ill, he could not attend the meeting.
→ As he was ill, he could not attend the meeting.
→ Because he was ill, he could not attend the meeting.
→ He could not attend the meeting because he was ill.
• It was raining. We did not go out.
→ Since it was raining, we did not go out.
→ We did not go out as it was raining.
Important Note: "Since" can also be used as a preposition of time meaning "from that time". Example: "I have been living here since 2020."
For POSITIVE comparison (equality):
For NEGATIVE comparison: Use "so - as" instead of "as - as"
• Ram is intelligent. Shyam is intelligent.
→ Ram is as intelligent as Shyam.

→ She runs as fast as her sister.

Important: "Unless" means "if not", so remove "not" from the condition sentence
• You do not work hard. You will fail.
→ Unless you work hard, you will fail.
• He does not come soon. We shall miss the train.
→ Unless he comes soon, we shall miss the train.
Similar to "if" but used for precautionary measures

→ Take an umbrella in case it rains.
Shows continuation up to a point in time
• Wait here. I return.
→ Wait here until I return.
• Keep trying. You succeed.
→ Keep trying until you succeed.
Similar to "if" but for hypothetical situations
• He comes late. What will we do?
→ Supposing he comes late, what will we do?
Used to show fear or precaution to avoid something bad:
Important: "Lest" is already negative, so remove "not" from the second sentence
• Walk carefully. You may fall down.
→ Walk carefully lest you should fall down.
• Work hard. You may not fail.
→ Work hard lest you should fail.
• Run fast. You may miss the train.
→ Run fast lest you should miss the train.
• Be careful. You may not get hurt.
→ Be careful lest you should get hurt.
Note: "Should" is mandatory after "lest". Also note how negative sentences become positive after "lest".
Shows that second action happened immediately after the first:
Note: Both sentences must be in past tense originally
• The teacher entered the class. The students stood up.
→ Hardly had the teacher entered the class when the students stood up.
→ Scarcely had the teacher entered the class when the students stood up.
• I reached the station. The train left.
→ Hardly had I reached the station when the train left.
• He heard the news. He started crying.
→ Scarcely had he heard the news when he started crying.
Remember: The structure is always: Hardly/Scarcely + had + subject + V3 + when + subject + V2
Same meaning as "Hardly-when" but uses "than" instead of "when":
• The teacher entered the class. The students stood up.
→ No sooner had the teacher entered the class than the students stood up.
• I reached the station. The train left.
→ No sooner had I reached the station than the train left.
• He saw the police. He ran away.
→ No sooner had he seen the police than he ran away.
Key Difference: Hardly/Scarcely use "when", but No sooner uses "than"
Simplest way to show immediate succession:
Note: This is much simpler than "Hardly-when" or "No sooner-than" and means the same thing
• The teacher entered the class. The students stood up.
→ As soon as the teacher entered the class, the students stood up.
• I reached the station. The train left.
→ As soon as I reached the station, the train left.
• He heard the news. He came to my house.
→ As soon as he heard the news, he came to my house.
• The bell rang. The students rushed out.
→ As soon as the bell rang, the students rushed out.
Tip: "As soon as" is the easiest option - use it when you're unsure about the complex structures of "Hardly/Scarcely-when" or "No sooner-than"
