What is copulative conjunction?

Hint: A conjunction is a component of speech that links the conjuncts of the conjunctions, which are words, phrases, or clauses. Because this definition may overlap with those of other elements of speech, each language must specify what makes a "conjunction."

Complete answer:
Copulative conjunctions (also known as additive conjunctions) are coordinating conjunctions that show that something has been added. The conjunction denotes that the second word, phrase, clause, or sentence conveys a fact that is linked to the first. and, also, as well as, furthermore, no less, and plus are some of the most prevalent copulative conjunctions.
For example,
My kangaroo has the ability to sing.
And she isn't half-bad.
Moreover, she received a Grammy award last year.
Plus, she is an excellent singer.

“Moreover” and “plus” come close to becoming adverbs in the final two phrases, altering the primary verbs of their sentences (won and the contracted is). Commas should be used to separate adverbial copulative conjunctions. It's also not necessary to make it distinct.

And is the sole copulative conjunction that may be used within a sentence to introduce a second independent clause, such as:
We ate lunch, and we took a nap.

Note: Disjunctive conjunctions are conjunctions that are employed in sentences to divide two or more mutually incompatible choices. When disjunctive conjunction is employed, it typically means that either one or none of the components connected by the conjunctions are true. But, either, else, neither, other, and otherwise are the most often used disjunctive conjunctions.
