Rules of Conjunction

Conjunction acts as a joiner and it connects the parts of a sentence.
Example:
I watched the movie and then I had my dinner at a restaurant on the last Friday night.

Coordinating Conjunctions:
But, and, yet, or, nor, for — the examples of coordinating conjunctions.

• When a coordinating conjunction connects two independent clauses, usually a comma (,) is used, but it is not mandatory for all the time.
Example:
Rabi wants to be a player in the school cricket team, but he cannot meet the criteria decided by the committee.

• The comma is correct in using when two independent clauses are joined with a coordinating conjunction.
Example: Vidya spends her vacation reading stories, novels, and writing poetries.

• When a coordinating conjunction connects the elements in a series, then comma (,) is not needed.
Example: I want sugar and milk and bread in the morning.

• A comma (,) is used with ‘but’ when it represents a contrast.
Example: This is a basic rule to write stories, but it is tough to remember.

Subordinating Conjunctions:
This type of conjunction is used to join a complete or independent clause with a dependent clause. Here, the dependent clause is placed by relying on the main clause. The subordinating conjunction is placed before the dependent clause.
Example: Since the time management skill is required, the students practice guess papers for each subject.
Here, ‘the time management skill is required’ is a dependent clause and the independent clause is ‘the students practice guess papers for each subject’.
The subordinating conjunction is ‘since’.

Correlative Conjunctions:
Correlative conjunctions refer the pairs of conjunctions that are used in a sentence to connect different words or a group of words. This type of conjunction usually joins the words, not the sentences. It connects the words of equal importance in a sentence.
Example: Both the dress and accessories are expensive at the shopping mall.
Here, ‘both/ and’ are correlative conjunctions. Dress and accessories are equally important elements.
Just as she needs a job so she brushes up her communication skill.
Here, ‘just as / so’ are correlative conjunctions.
It doesn’t matter whether you get a good score or not, put your efforts in the exams.
‘Whether/or’ are correlative conjunctions and it represents two different options.

Some conjunctive adverbs are mentioned below:
As a result, Hence, Finally, However, After all, Indeed, In fact, Instead, Moreover, Nonetheless, etc.
