complementary relationship | Select relationship | exclude/include relationships |
and…as well as both…and not only…but also | either…or neither…nor | not…but |

Linking adverbs can connect two independent clauses and express the meaning relationship between clauses. Conjunctive adverbs can also serve as transition words between two sentences. Linking adverbs can express complement, explanation, contrast, cause and effect, condition or temporal relationship.
In a complete sentence, a connecting adverb is placed between two independent clauses. Use a semicolon after the first clause and a comma after the connecting adverb. When a connecting adverb is used as a transition word between two sentences, a comma should be added after it and placed at the beginning of the second sentence.
