Conjunctive adverbs, also known as sentence connectors or transitional words, are crucial in business, technical, and academic writing as they connect whole sentences. They require careful selection based on the relationship between the sentences, especially when indicating results or contrasts. Proper punctuation is essential, typically involving a semicolon or period after the first sentence and a comma after the conjunctive adverb.

1. CONJUCTIVE ADVERDS
Conjunctive adverbs (which are sometimes also called
sentence connectors or transitional words) are commonly
used in serious business, technical, and academic writing.
Conjunctive adverbs are, similar in meaning to other types
of connecting words such as and, but, or, etc., but they
have one very important difference: they join sentences,
not parts of sentences.

2. Conjunctive adverbs (or sentence connectors or
transitional words) join sentences, not parts of sentences.
In choosing a conjunctive adverb to use in connecting
sentences, the relationship between the sentences that
are to be connected is very important.
When what happens in one sentence is the result of what
happened in the preceding sentence, only a few conjunctive
adverbs can be used. The most common ones for this
situation are therefore, as a result, consequently, and
accordingly. All of these mean the same thing and are
used in the same way.

3. CONJUCTIVE ADVERBS ALSO
HAVE SPECIAL PUNCTUATION
Conjunctive adverbs also have special punctuation:
with them, a semicolon or a period is used after the first
sentence, and a comma is usually used after the conjunctive
adverb. After the comma, the connected sentence follows.
Following are some common conjunctive adverbs, plus
general comments on their usage:

ideas and information that they connect. There will be
