Conjunctions

Conjunctions are mainly of three types:

1. Coordinating conjunctions: and, but, or, nor, for, yet, so
2. Subordinating conjunctions: although, because, since, if, when, etc.
3. Correlative conjunctions: either.or, neither.nor, not only.but also.

When a conjunction is used to connect two independent clauses, a comma should be used before the conjunction.

To conclude, conjunctions are vital to constructing well-formed sentences in English. Whether writing or speaking, using the right conjunctions will help one convey their message more clearly and effectively.

Yes, it is acceptable to begin a sentence with conjunctions like "but," "and," or "because," but they should be used sparingly.

Coordinating conjunctions connect clauses of equal grammatical weight (e.g., two independent clauses) whereas Subordinating conjunctions (like because, although, while) connect an independent clause to a dependent clause and show the relationship between them (cause, time, contrast, etc.).
Example (Coordinating): He was tired, yet he kept running.
Example (Subordinating): Although he was tired, he kept running.

Yes, in informal speech or writing, conjunctions may sometimes be omitted for brevity.

Conjunctions are used to connect words, phrases, or clauses, allowing us to express more complex and meaningful thoughts in a simpler and smooth way.
