While writing, a list of conjunctive adverbs may be helpful for some people. The purpose of a conjunctive adverb is to show a relationship between clauses such as comparing or contrasting, showing a sequence of events, or showing a cause and effect.
An adverb is a part of speech that modifies a verb,
adverb, adjectives, clauses, and sentences, anything
but a noun. Many adverbs end in -ly, although not all of them.
A conjunction is a part of speech that connects phrases
and clauses. Therefore, a conjunctive adverb is a type
of adverb that joins together two clauses. These clauses
are usually independent clauses, otherwise known as
You must do your homework; otherwise, you might get a bad grade.
I will not be attending the show. Therefore, I have extra tickets for anyone that can use them.
Amy practiced the piano; meanwhile, her brother practiced the violin.
Marion needed to be home early. Consequently, she left work at 3 p.m.
To correctly punctuate a conjunctive adverb,
a writer will use a semicolon or period at the
end of the first independent clause. The conjunctive
adverb is then used followed by a comma and the
next independent clause.
