Answer:
In English, connecting words are called conjunctions. Conjunctions are used to connect words, phrases, and clauses in a sentence. There are three main types of conjunctions: coordinating conjunctions, subordinating conjunctions, and correlative conjunctions.
Coordinating conjunctions are used to connect words or groups of words that have the same grammatical structure. The most common coordinating conjunctions are: for, and, nor, but, or, yet, and so. These conjunctions are usually used to connect two independent clauses in a sentence. For example:
I'm going to the store, and I'll pick up some milk.
In this sentence, the coordinating conjunction "and" is used to connect the two independent clauses "I'm going to the store" and "I'll pick up some milk."
Subordinating conjunctions, on the other hand, are used to connect a dependent clause to an independent clause. A dependent clause cannot stand on its own as a sentence, so it must be connected to an independent clause to form a complete sentence. Some common subordinating conjunctions are: after, although, as, because, before, if, since, unless, until, and while. For example:
I'll stay home because I'm feeling sick.
In this sentence, the subordinating conjunction "because" is used to connect the dependent clause "I'm feeling sick" to the independent clause "I'll stay home."
Correlative conjunctions are pairs of conjunctions that are used together to connect words or groups of words. Some common correlative conjunctions are: either/or, neither/nor, both/and, not only/but also, and whether/or. For example:
I'll either go to the movies or stay home and watch TV.
In this sentence, the correlative conjunction "either/or" is used to connect the two choices "go to the movies" and "stay home and watch TV."
When using conjunctions in your writing, it's important to remember that they should be used to clarify the relationship between the words, phrases, and clauses in your sentence. Using too many conjunctions can make your writing confusing and difficult to understand, so try to use them carefully and only when they are necessary.
