Compound থেকে Complex এ পরিবর্তন করার নিয়ম

A compound sentence is characterized by at least two independent clauses which can be used as separate sentences and are connected with coordinating conjunctions.

একটি compound sentence এ কমপক্ষে দুটি independent clause থাকে যারা পৃথক sentence হিসেবে ব্যবহৃত হতে পারে এবং  coordinating conjunction দিয়ে  যুক্ত থাকে ।

Such as, Listening to music and singing songs are my hobbies.

On the other hand,  a complex sentence is characterized by one independent clause and at least one dependent clause.

পক্ষান্তরে Complex sentence এ একটি independent clause এবং কমপক্ষে একটি dependent clause থাকে।

Such as, I will wait here until you come.

The rules for transforming compound sentence to complex sentence are discussed below.

Compound sentence কে complex sentence এ রূপান্তরিত করার নিয়ম নীচে বর্ণিত হলো ।

Rule 1:

If the compound sentence uses the conjunction “but”/”yet” to connect the different clauses, the complex sentence will use “though”/”Although” in the beginning and “but”/”yet” will be removed.

Compound sentence “but”/”yet” conjunction দিয়ে পৃথক clause গুলোকে যুক্ত করলে, Complex sentence এর শুরুতে “though”/”Although” বসে “but”/”yet” উঠে যাবে ।

Compound: He is poor, but he is happy.

Complex: Though he is poor, he is happy.

Compound: She is ill, yet she worked very hard.

Complex: Although she is ill, she worked very hard.

Compound: The class was lengthy, but it was enjoyable.

Complex: Though the class was lengthy, the class was enjoyable.

Rule 2:

If the compound sentence uses the conjunction “or”/”otherwise” to connect different clauses and future tense is used in the second clause, the complex sentence uses “lest” in the middle and “should” after the person.

যদি Compound sentence এ conjunction “or”/”otherwise” ব্যবহার করে পৃথক clause গুলোকে যুক্ত করা হয় এবং দ্বিতীয় clause এ future tense হয়, তবে complex sentence এর মাঝে  “lest” হবে এবং person এর পরে “should” বসবে ।

যদি compound sentence “and”/ ”so”/ ”hence”/ ”therefore” দিয়ে পৃথক clause গুলোকে যুক্ত করে, তবে complex sentence এর শুরুতে “since”/ ”as”/ ”when” বসে “and”/ ”so”/ ”hence”/ ”therefore” উঠে যাবে ।
