* New words and phrases are constantly evolving: Language is dynamic, and new conjunctions can emerge or become popular over time.
* Degrees of formality: Some words act as conjunctions in certain contexts but not in others. For example, "so" can be a conjunction ("I was tired, so I went to bed") or an adverb ("I was so tired").
* Subcategories: There are many different types of conjunctions (coordinating, subordinating, correlative, etc.), and the lines between them can blur.
Instead of focusing on a specific number, it's more helpful to understand the different types of conjunctions and how they function in sentences.
Here are some major categories:
* Coordinating conjunctions: These connect words, phrases, or clauses of equal grammatical rank. Examples: and, but, or, nor, for, yet, so.
* Subordinating conjunctions: These connect a dependent clause to an independent clause. Examples: because, although, since, while, if, unless, before, after.
* Correlative conjunctions: These come in pairs to connect equal grammatical elements. Examples: both...and, either...or, neither...nor, not only...but also.
By understanding these categories and their uses, you can effectively use conjunctions to create complex and grammatically correct sentences.
