Are conjunction and conjunctive the same thing?

No, "conjunction" and "conjunctive" are not the same thing. They are related, but they are different parts of speech:

* Conjunction: This is a word that joins words, phrases, or clauses. Examples include "and", "but", "or", "because", "so", "yet", etc.

* Conjunctive: This is an adjective that describes something that is related to conjunctions. It is often used to describe words, phrases, or clauses that are joined by conjunctions.

Here are some examples:

* Conjunction: "I went to the store and bought some milk." ("and" is the conjunction)

* Conjunctive: "The conjunctive phrase 'and bought some milk' adds information to the sentence."

So, while they are both related to joining things together, a conjunction is a specific type of word, whereas conjunctive is a broader descriptor for something that relates to conjunctions.
